Explanation:

Carbon compounds are the energy source of cellular respiration. These molecules are oxidized, that is, they lost their electrons, in order create energy for the cell. For example, we could start with a large lipid chain of 16 carbon atoms, that will experience oxidation in order to create conditions for ATP synthesis, that finally will become one carbon atom. Single carbon atoms are exhaled in respiration as CO2 (Carbon dioxidde). So, carbon atoms are the source of energy in cellular respiration (as carbon molecules), and finally they serve as a mean to exhale the metabolic waste, as CO2.

The reproductive part which is responsible for carrying eggs of the uterus is the oviduct, also known as fallopian tubes after they are produced in the ovary of a woman. There will be the structure sperm have to reach to occur in fertilization and the posterior formation of an embryo.

The correct answer then is the last one: oviduct.

Biology > Cell biology > Passive transport

There are different types of transport in the cell that can be classified into two groups: passive transport (which does not require energy) and active transport (which requires energy because it goes against the concentration gradient).

Diffusion is a type of passive transport and it does not require energy, it can be divided into simple diffusion (molecules pass through the membrane without the help of any channel) and facilitated diffusion (molecules pass through the membrane with the help of a protein channel).

Facilitated diffusion will transport certain molecules and simple diffusion others. Larger, polar and charged molecules will need help to cross the membrane, so they will do so by facilitated diffusion. Therefore, the answer is D.

A mutation is due to changes in the b. nucleic acids.

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

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.

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.

Energy flows through the ecosystem, but no new energy is created. The sun represents a constant input of new energy to the ecosystem. Autotrophs use this energy to create chemical energy and inorganic matter to make organic compounds, thus making the energy provided by the sun available for the other components of the energy flow chain.

Without "producers" making energy available for all other links, the amount of "new" energy flowing through the system will decrease.

On the other end of the energy flow system, you find the "decomposers", the organisms in this group are in charge of degrading the organic remains of dead organisms, as well as metabolic waste products. These organisms are in charge of making the energy stored in the organic remains available for other groups of the system to use. Without the members of this group, the energy stored in the remains wouldn't be able to reenter the cycle and the energy levels, usually conserved, will drop greatly.

Out of both groups, the "producers" are in charge of producing and recycling energy, and the "decomposers" are in charge of "recycling" the energy stored in organic remains, the one whose absence will cause a greater drop in energy will be the decomposers.

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.

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).

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 percentage of offspring who can teleport is 50%, and 50% who cannot.

Both superheroes can teleport. For both, one of their parents was a purebred dominant and the other a purebred recessive.

75% of the offspring will be able to teleport, and 25% won't.

The complete equation of photosynthesis is shown in the image attached to the answer. Carbon dioxide and water are the reactants while glucose and oxygen are the products.

We know that the process of photosynthesis has to do with the process by which there is the combination of carbon dioxide and water and these would now lead to the formation of the sugars that we have in photosynthesis.

It is the sun that acts as the catalyst of the process and then the light from cell would  fall on the green pigment of the plant as the process is underway in the system of the plant.

Cell theory states that all organisms are made of cells, that they are the basic structure of all organisms, and that each cell is made of a preexistent cell.

These three statements are the principles of the cell theory.

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.

In addition to promoting or discouraging the production of hormones in the pituitary gland, the hypothalamus secretes hormones that control blood pressure, appetite, sleep, temperature, and water balance. So, option D is the proper response.

Controlling vital biological functions and overall health depends on the pituitary gland, a tiny organ about the size of a pea. Because it regulates the activity of the majority of other glands that secrete hormones, it is known as the body's "master gland."

The anterior pituitary gland creates the hormones, which are then released into the bloodstream under the control of releasing or inhibiting signals from the hypothalamus and the level of circulatory hormones.

The posterior pituitary gland stores two hormones that are created by the hypothalamus before they are released into the bloodstream.

Which are:

Vasopressin, a hormone that regulates blood pressure and water balance, is an antidiuretic hormone.

Oxytocin promotes milk production during breastfeeding and uterine contractions during childbirth.

Precipitation is the condensation of water vapor to droplets. It forms clouds that when it contains a lot of water droplets will fall into the ground, and we call it "rain".

Runoff is when the flow of water is in excess and the land cannot absorb it fast.

In both processes, gravity acts on the flow of water. During precipitation, gravity pulls the droplet down from the atmosphere. During a runoff, the flow of water goes down from the side of the mountains to the streams and rivers. Both can also be observed in a water cycle.

yes, Allen is correct about her summary, in fact, a piece of additional information to Allen's would be:

The kudzu plant was brought from Asia and introduced in the United States in the late 19th century to be used for ornamental purposes. However, this plant was widely cultivated in the south of that country in the early 20th century to reduce soil erosion. However, this plant would quickly colonize the landscape, growing about a foot a day and covering the ground, shrubs, trees, and even old things with a suffocating blanket of creepers. Kudzu can cause environmental damage as it is an invasive plant. In fact, the environmental and ecological damage of Kudzu results from its competition with other plant species. In particular, kudzu competes with native flora for light and acts to block their access to this vital resource by growing over them and shading them with its leaves. Native plants may die as a result. The problem with Kudzu is that it grows out of control quickly, spreading through stolons (stems that root at the tip when in contact with moist soil), rhizomes, and creepers that root at nodes to form new plants. On the other hand, according to scientists at Clemson University, its spread could accelerate climate change by reducing the carbon reserves stored in the soil of the ecosystems it colonizes, as in the case of this Mississippi forest.
