Veins carry blood that has very low pressure and have valves to control the one-way flow of blood. The rest are false. Only the pulmonary vein carries oxygenated blood. Arteries have more smooth muscles than veins. The anastomoses are present to act as alternative pathways to reach cells.

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

light intensity does not affect the rate of 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.

Answer:

A

Explanation:

When the population is well below the carrying capacity, it results into Logistic Growth.

As competition increases and resources become increasingly scarce, populations reach their carrying capacity causing growth rate to slow nearly to zero.

This produces an S-shaped curve of population growth known as the Logistic Curve.

Resources important for the survival of the species can act as a factor for Carrying Capacity .Example- For plants , it is water, sunlight, nutrients and space and for Animals- Food, Water, Shelter and Nesting Space.

Limited quantities of these resources results in competition between members of the same population or Intraspecific competition.

Examples of Logistic Growth are:

Yeast - A microscopic fungus can produce S shaped curve when grown in test tube.

Logistic Growth takes place when population's per capita growth rate decreases as population size approaches a maximum imposed by limited resources i.e. the carrying capacity.

Ecologists uses different methodologies for modelling Population Dynamics, amongst which major ones are Exponential Growth and Logistic Growth.

When the per capita rate of increase takes the same positive value regardless of the population size, it results into Exponential Growth whereas the per capita rate of increase decreases as the population increases towards a maximum limit, then we get Logistic Growth.

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%.

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.

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

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.

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.

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:

2.4 × 10⁻⁶ M

Explanation:

Molar concentration = no of moles of solute (enzymes)/volume of solvent(cystosol)

Let V = volume of solvent = volume of cystosol = πd²h/4 where d = diameter of cell = 1.0 m and h = height of cell = 2.0 m

Concentration of enzymes, C = n/V where n = no of moles of enzymes

Also, n = m/M where m = mass of all enzymes and M = molecular weight of protein = 100,000

Note that the solvent for the enzymes is cystosol, since they are dissolved in it.

Density of cystosol,ρ = specific gravity of cystosol in g/cm³ = 1.20 g/cm³.

Now, ρ = m'/V where m = mass of cystosol and V = volume of cystosol

m' = ρV

m' = 1.20V

Given that 20 % of the cystosol is protein and all protein are enzymes, the mass of enzymes is thus m = 0.2m' = 0.2 × 1.20V = 0.24V

C = n/V

= m/MV

= 0.24V/100000V

= 2.4 × 10⁻⁶ mol/cm³

= 2.4 × 10⁻³ mol/dm³

= 2.4 × 10⁻³ M

This is the concentration of all the 1000 enzymes.

So, the concentration of one enzyme is 2.4 × 10⁻³/1000 M = 2.4 × 10⁻⁶ M

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.

Answer:

Mendel's law of independent assortment states that the alleles of two (or more) different genes get sorted into gametes independently of one another. In other words, the allele a gamete receives for one gene does not influence the allele received for another gene. Let's look at a concrete example of the law of independent assortment.
