Both the brain and spinal cord are protected by ____.

This question must be approached carefully, protists as a kingdom include protozoans and algae, from this the only ones that do photosynthesis are algae, therefore if we talk of protists as kingdom we can say that is true if we talk of protists as protozoans is false.

The correct answer is "parental generation", since this inter-breeding refers to pure races/genotypes, that potentially could generate any genotype combination.

The asexual reproduction or clonal production, of a diploid egg that is activated but not fertilized by the prescence of sperm is a proccess called parthenogenesis (optionB).

Naturally occurring variation in the genetic information on a segment of DNA among individuals is referred to as mutation. When a cell divides and produce a copy of DNA, mutation can sometime happen when the copied DNA is not perfect. This slight change from the model DNA is called as mutation.

Answer - Option C - Mutation

The fourth correct answer is that sedimentary rock is where fossils are most frequently found.

The preserved remnants of animals and plants that were submerged in sediments like sand and mud beneath ancient seas, lakes, and rivers are known as fossils. Any preserved sign of life that really is typically older than 10,000 years is considered a fossil. Any surviving remains, impression, or evidence of a once-living thing from such a previous geological epoch is referred to as a fossil. Examples include fossilized bones, shells, exoskeletons, animal or microbe imprints in stone, amber-preserved artifacts, hairs, petrified woods, oil, coal, and DNA traces.

According to State of New York Geological Survey, fossils are made through a variety of various chemical and physical processes. Whole-body fossils can be formed by freezing, drying, and encasing in tar or resin to preserve bodily tissues. The first dinosaurs bone was reportedly found in 1677 by Robert Plot, who initially thought it belonged to a huge human. The first geology professor at Oxford University, William Buckland, was the one who first accurately recognized a dinosaur fossil as such.

Sedimentary Rocks: Rocks that are produced from previously existing rocks or fragments of once-living organisms are known as sedimentary rocks. They emerge from deposits that amass on the Earth's surface. Identifiable bedding or layering is typically present in sedimentary rocks.

The two major parts of the earth system that this photo most clearly shows are the lithosphere and hydrosphere.

Earth systems refer to the various systems of the earth that compose the earth.

The major earth systems are as follows:

Lithosphere - this is the hard layer of the earth which includes the earth's crust such as deserts, mountains, etc.

Hydrosphere - this is the earth system that is composed of water such as the oceans, rivers, streams, etc.

Atmosphere - this is the earth's system that is composed of the layers of gases above the earth's crust.

Diabetes can result from elevated levels of glucose in blood. Hypothermia can be observed when the body is subjected to extreme cold temperatures for a long duration. Hyperthermia can occur when the body is exposed to extreme high temperatures for a long time.

Diabetes is caused due to increased levels of glucose in the blood. It is a medical condition that is usually associated with the deficiency or improper functioning of the Insulin hormone.

Hypothermia is a condition which develops from exposure to extremely low temperatures, i.e. below 95.0 °F, for a long period of time. Its symptoms may vary according to the temperature. Severe hypothermia can be fatal. Hyperthermia is the opposite condition, where the body temperature remains elevated abnormally for a long time.

NADH is the Nicotinamide adenine dinucleotide e FADH2 is the Flavin adenine nucleotide, both of them are high energy electron carriers. They are reponsible for transporting electrons generated in Glycolises and Krebs Cycle to the Electron Transport Chain, creating ATP.The difference between them is that a NADH molecule produces 3 ATP molecules while a FADH2 molecule produces 2 ATP molecules.

Assuming the shape of wings is coded by a diallelic gene expressing complete dominance, in the proposed cross the parental genotypes are vv and +v. And the progeny genotypes are vv and +v.

In genes that express complete dominance, one of the alleles completely hides the expression of the other allele in heterozygous individuals.

In these cases, even when the individual is carrying both alleles, the expressed phenotype is the dominant one.

In fruit flies,

In the cross,

Half of the progeny expressed vestigial wings and the other half expressed the wild type.

We know the male could only transmit the recessive allele.

If there are individuals expressing the recessive phenotype among the progeny, it means that the female is heterozygous and it transmitted a dominant and a recessive allele.

If the female was homozygous dominant, the whole progeny would be heterozygous and would express the dominant phenotype.

Solution:

The correct answer is:

Yes, Kudzu helps prevent erosion.

Explanation:

Kudzu is a leafy vine that can prevent soil erosion. This is due to its wide leaves and strong root system that prevents soil erosion. In fact, Kudzu exhibits a symbiotic relationship with nitrogen-fixing bacteria, which may help explain their successful growth on heavily eroded sites. The kudzu cover prevents soil erosion because produces a high density of organic matter and this slows down the speed of rainwater. Also, Kudzu maintains soil moisture and prevents runoff even on steep slopes.

Photosynthesis is the process in which the chloroplasts transform the energy from sunlight into biochemical energy and store it in ATP molecules.

Cell respiration is the process in which biochemical energy is synthesized by the mitochondria.

The correct answer is "mitochondria"

No, this is not accurate. It could be reworded as Recent studies have revealed that kudzu's effects are more problematic than previously believed.

Fast-growing invasive plants like kudzu outcompete anything from native grasses to fully developed trees by blocking the sunlight needed for photosynthetic activity.

Because it suffocates other plants and trees under a canopy of leaves, taking all the sunshine and trapping other species in its shade, kudzu is very terrible for the ecosystems that it invades.

Due to its aggressive nature, kudzu has a variety of negative ecological effects, such as shading out native plants in forest understories, changing the chemistry of soil by fixing nitrogen, and reducing native biodiversity.

Breast cancer is a multifactorial disease so the risk factors can be varied. However, the main factors are gender and age, since most breast cancers are detected in women over 50 years of age. Other risk factors that cannot be avoided include genetic mutations in genes such as BRCA1 and 2, having early menstruation and late menopause, as there is exposure to hormones for a longer time, having relatives with breast cancer and having received radiotherapy.

It should be noted that there are also risk factors that can be avoided. These include taking hormone treatments, not exercising, being overweight, drinking alcohol and getting pregnant for the first time after the age of 30. Fortunately, these factors can be reduced by exercising, eating a healthy diet, and receiving reproductive and hormonal counseling from a physician.

ANSWER: B.

Part 1. Photosynthesis is a means to transform light energy from the sun to stored chemical energy. This is done by converting CO2 that enters into the leaves of a plant with the addition of H2O to form sugar and O2. O2 is released as the by-product of photosynthesis. Sugar is where the chemical energy is stored.

This is the chemical equation of photosynthesis:

6CO2 + 6H2O → C6H12O6 + 6O2

So as you say, ATP is a molecule involved in energy generation. This molecule, Adenosine Triphospate is a nucleotide comformed by a nitrogenous base (adenosine), and by a pentose sugar, and in fermentation is carried out by glucolisis due to the absent of oxygen, producing only 2 molecules of this ATP.
