Answer:
a) temperature
Explanation:
took test and got right
light intensity does not affect the rate of photosynthesis .
what is photosynthesis ?The process in which plants, algae and certain bacteria use light energy of sunlight, water, carbon dioxide and convert light them into chemical energy and starch. called as photosynthesis.
Photosynthesis occur in special organelles named chloroplast which has its own DNA, genes and hence can synthesize their own proteins.
Chloroplasts have stroma, fluid, and stack of thylakoids known as grana, three types of chlorophyll such as chlorophyll a, chlorophyll b, and carotenoids.
Oxygenic photosynthesis is commonly observed in plants, algae and cyanobacteria where electrons are transferred from water to carbon dioxide by using light energy, to produce energy, oxygen is produced along with carbohydrates.

Sally, 9-year-old girl, just did an awesome backflip on her trampoline. Instead of landing in a similarly awesome manner, she miscalculated and landed on her neck. Sally stood up with pain in her neck and does not appear to be able to extend her left arm very well. An x-ray shows a fracture of her C6 vertebrae that is compressing down on her C7 vertebrae impacting the spinal nerve located between C6 and C7 vertebrae. Which spinal nerve did Sally likely injure
Answer:
The C7 spinal nerve
Explanation:
The C7 spinal nerve exits on each side through the intervertebral foramen between the C6 and C7 vertebrae. The C7 spinal nerve has both a sensory root which is composed of sensory fibers and a motor root. This nerve is required to control motor functions including shoulder movement (i.e., adduction, abduction and rotation). The C7 dermatome is a region of skin that receives sensory inputs from the C7 spinal nerve.
In one of these systems, the prey are very large animals and the predators are verysmall animals, such as elephants and mosquitoes. Thus it takes many predators toeat one prey, but each prey eaten is a tremendous benefit for the predator population.The other system has very large predators and very small prey. Determine whichsystem is which and provide a justification for your answer.
Answer:
Due to its size and feeding requirement.
Explanation:
In the forest ecosystem, many lions feeds on one deer or buffalo because the food is in large amount and this food is enough to fulfill the requirements of that lions so we can say that many predators eats one prey while on the other hand, there are some predators that feeds on many prey at one because they are small in size and one prey did not fulfill their requirement so that's why the predator feeds on many preys. Fox feeds on many mice is the example of one predators feed on many prey.

7. Apply: Look carefully at the picture below and you will see an insect called a
katydid. Katydids evolved from grasshoppers through natural selection. Use
what you have learned to explain how this could have happened.
Answer: This description is an example of camouflage adaptations.
Explanation:
The grasshoppers are the insects which feed on plant parts and they are able to change their color with respect to their surrounding environment. For example, if they are living on the brown tree trunk they change their color to brown and on the green grass or green leaves they change to green to remain undetected by the predators. This way they are able to camouflage their predators this adaptation allows their survival in their environment with due course of natural selection. The phenotypic trait that is grasshopper is able to change its color increases the chances of survival of the grasshopper. Kaytids have evolved from grasshoppers means they have camouflage traits as that in parent grasshopper species. They have structure which blends with surrounding environment, that is they have wings that mimic that of pattern of leaf venation, also when they change the color to brown the shape of the body appears to be as that of stem. This structural adaptation help them to camouflage their predators.

Given a DNA sequence of ACG, what would be the corresponding RNA sequence? Once you determine the RNA sequence, what would be the corresponding amino acid for the RNA codon? Would a change in one nucleotide of the DNA alter the corresponding amino acid? Explain.
Answer:
- RNA sequence: UGC
- Amino acid sequence: Cysteine
- Yes, a change in nucleotide will alter the amino acid.
Explanation:
According to this question, a DNA sequence was given as follows: ACG. The process of transcription will produce a RNA sequence from this DNA sequence using complementary base pairing i.e. A-U, G-C etc. Based on this, the mRNA sequence that will result of the DNA sequence above is UGC.
The resulting mRNA transcript is a codon (three nucleotides) that will be used in the process of translation to yield an amino acid. The mRNA sequence: UGC codes for amino acid Cysteine.
- A change in one nucleotide of the DNA will alter the corresponding amino acid because DNA sequence in a particular reading frame is responsible for the production of amino acid. Hence, a slight change in nucleotide might change the reading frame of the sequence and hence give rise to a different amino acid.

Answer:
C. There is a 25% chance of short offspring.
Explanation:
In the simplified genotypes of a Punnett square cross, we deal with two genotypes. In this case, we are looking at a cross between Tt and Tt. T is dominant and t is recessive, meaning that someone with any genotype with T in it will be tall.
TT, Tt, and Tt will all produce tall offspring, while tt will produce short offspring.
This means there is a 75% chance of tall offspring, or 3:4.
50% or 2:4 are expected to have the Tt genotype.
Only 1 of the 4 will produce short offspring, which is 25%.
Select all that apply.

Why are most systems in the human body negative feedback systems?
Most systems in the human body are negative feedback systems because negative feedback systems allow humans to regulate and stabilize their systems, which is the first option as a negative feedback system regulates the body's functioning.
What is the negative feedback system?Negative feedback is a regulatory mechanism in which a change in a physiological variable triggers a response that opposes the initial change, for example, in the regulation of body temperature, when the body becomes too hot, thermoreceptors in the skin and other tissues detect the change in temperature and send signals to the hypothalamus, which acts as the body's thermostat and as a feedback mechanism, hypothalamus triggers responses that cool the body, such as vasodilation to increase blood flow to the skin, sweating to release heat, etc.
Hence, most systems in the human body are negative feedback systems because negative feedback systems allow humans to regulate and stabilize their systems, which is the first option.

Phenylketonuria (PKU) is a genetic disease caused by the inability to break down the amino acid phenylalanine. If untreated it leads to severe mental disabilities. PKU is due to a recessive allele. Assume that the US population is in Hardy-Weinberg equilibrium with respect to this gene. In the US the PKU rate is 1 out of every 10,000 babies born. What percent of the US population have no alleles for PKU
Answer:
Therefore, 98% of the US population have no alleles for PKU
Explanation:
The Hardy-Weinberg equilibrium states that the amount of genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.
The Hardy-Weinberg equilibrium is expressed quantitatively using a mathematical equation known as the Hardy-Weinberg equation. the equation is given below:
p² + 2pq + q² = 1
also, p + q = 1
Given a pair of alleles, S and s with A dominant and a recessive
where p is the frequency of the dominant allele in the population,
q is the frequency of the recessive allele in the population,
p² represents the frequency of the (SS) dominant genotype,
q² represents the frequency of the (ss) recessive genotype,
2pq represents the frequency of the heterozygous genotype
From the given question,
q² = 1/10000 = 0.0001
q = 0.01
from p + q = 1
p = 1 - 0.01 = 0.99
p² = 0.98
Therefore, 98% of the US population have no alleles for PKU

Which of the following best describes how independent assortment results in inherited variations within a species and how it contributes to evolution?
A Independent assortment results from the copying of DNA during cell division and causes variations that are sometimes beneficial to a species
B Independent assortment results from the binary fission of a single cell and causes mutations that can be beneficial or harmful to a species
C Independent assortment occurs during mitosis and causes uncontrolled cell division which is harmful to a species
D Independent assortment occurs when chromosomes separate during meiosis and causes variations that can be beneficial or harmful to a species
Answer:
D Independent assortment occurs when chromosomes separate during meiosis and causes variations that can be beneficial or harmful to a species
Explanation:
During meiosis, the homologous chromosomes separate and segregate independently of each other. This process is referred to as 'independent assortment'. In consequence, different gene variants or 'alleles' localized in homologous chromosomes segregate independently of each other during gamete formation, thereby one particular gamete has an equal probability to carry either of these segregating alleles. Independent assortment generates genetic variation in the gametes, which can be beneficial or deleterious in a given environment.
The option that best describes how independent assortment results is D Independent assortment occurs when chromosomes separate during meiosis and causes variations that can be beneficial or harmful to a species
What is independent assortment ?Independent assortment is a phenomenon that occurs during meiosis, which is the process of cell division that produces gametes (sex cells). During meiosis, the chromosomes are randomly sorted into the gametes. This means that the alleles (different forms of a gene) on different chromosomes can be inherited together or separately.
This random assortment of alleles can lead to new combinations of traits, which can be beneficial or harmful to a species.

Why aren't there many large carnivores?
Answer:
Technically, the largest ever marine predator known thus far - the blue whale - is, for now, alive and well, but I know what you mean. You’re not talking about filter-feeders, or fish-eaters, you mean macropredators.
The last truly enormous macropredator in our oceans was probably Carcharocles megalodon, which went extinct about 3.6 million years ago. Other recent examples include the terrifying sperm whale Livyatan melvillei (which disappeared 8.9 mya) and other megatoothed sharks like C. chubutensis.
So, why did the giants go away? The answer, in truth, is likely multi-faceted. Here are some major promising hypotheses, or at least contributing factors:
Whales have declined. Giant sea carnivores like C. megalodon and Livyatan relied on marine mammals - specifically baleen whales. During the Pliocene, the Americas connected and the Central American Seaway was closed. This seems to have triggered a significant decline in the diversity of tropical whales, and would thus limit food availability for huge, energy-hungry predators.
Things got too cold. The extinction of megalodon and other giant ocean predators roughly coincides with the trend of decreasing temperatures the Pliocene brought. Giant sharks in particular, not being fully warm-blooded, would suffer from this, and it would also mean a decline in food supply. You can even see a sudden cold snap just about when Carcharocles went extinct, 3.6 mya.
Smaller predators outcompeted them. The niche of Carcharocles and the macroraptorial sperm whales is arguably still filled today - by the killer whale. Many orca pods specialize in hunting whales or other marine mammals. However, killer whales and their ancestors were perhaps more opportunistic, fast, intelligent and indeed adaptable than the massive, solitary hunters.
Ironically, the largest ever marine predator owes its existence to the demise of the largest ever marine macropredators. Since the extinction of macroraptorial sperm whales and Carcharocles megalodon, baleen whales have been gradually increasing in size, for they no longer need to be as fast and agile. Because of this, we have the privilege of sharing our world with the largest animal known to have ever lived - the blue whale.
