Answer:

Estrogen

Explanation:

Estrogens are a group of hormones that play an important role in the normal sexual and reproductive development in women.

Estrogen is responsible for the development of these characteristics in the female. Therefore, option (A) is correct.

Estrogen, also known as oestrogen, is a class of sex hormone that is responsible for the growth and regulation of the female reproductive system as well as secondary sex characteristics. Estrone, estradiol, and estriol are the three primary endogenous estrogens that are responsible for the majority of the hormone activity associated with estrogen.

The growth, development, and physiological functioning of the human reproductive system are all controlled by estrogen. In addition to affecting the neuroendocrine and skeletal systems, this hormone also affects the adipose and cardiovascular systems. Estrogen is a vital component of the male and female reproductive systems and is primarily manufactured by the ovaries in females and the testes in males.

The statement 'more new species have evolved in coral reef habitats than in most other types of habitats.' is accurate. A coral reef is a hotspot of biodiversity.

A coral reef is a marine ecosystem composed of organisms (i.e., corals) that form a wall together (i.e., reef-building corals).

These reefs consist of many colonies of coral polyps, which held together by a calcareous material (i.e., calcium carbonate)

A coral reef is a hotspot of biodiversity because there are many different species that live and evolved in this type of habitat.

4th- being more adaptive to the surroundings

Answer:

The lights higher on the light spectrum, like blue would have the fastest rate of photosynthesis because the energy is the highest. the green light would have the slowest rate because the chlorophyll inside of the leaves reflects green light, so it would not be absorbed as mich as the other colors. The color matters because the color or wavelength of light does affect photosynthesis, which is how plants can create their own food.

Explanation:

There are a few types of atoms that can be a part of a plant one day, an animal the next day, and then travel downstream as a part of a river’s water the following day. These atoms can be a part of both living things like plants and animals, as well as non-living things like water, air, and even rocks. The same atoms are recycled over and over in different parts of the Earth. This type of cycle of atoms between living and non-living things is known as a biogeochemical cycle.

All of the atoms that are building blocks of living things are a part of biogeochemical cycles. The most common of these are the carbon and nitrogen cycles.

Tiny atoms of carbon and nitrogen are able to move around the planet through these cycles. For example, an atom of carbon is absorbed from the air into the ocean water where it is used by little floating plankton doing photosynthesis to get the nutrition they need. There is the possibility that this little carbon atom becomes part of the plankton’s skeleton, or a part of the skeleton of the larger animal that eats it, and then part of a sedimentary rock when the living things die and only bones are left behind. Carbon that is a part of rocks and fossil fuels like oil, coal, and natural gas may be held away from the rest of the carbon cycle for a long time. These long-term storage places are called “sinks”. When fossil fuels are burned, carbon that had been underground is sent into the air as carbon dioxide, a greenhouse gas.

Recently, people have been causing these biogeochemical cycles to change. When we cut down forests, make more factories, and drive more cars that burn fossil fuels, the way that carbon and nitrogen move around the Earth changes. These changes add more greenhouse gases in our atmosphere and this causes climate change.

Carbon cycleThe Carbon Cycle

The element carbon is a part of seawater, the atmosphere, rocks such as limestone and coal, soils, as well as all living things. On our dynamic planet, carbon is able to move from one of these realms to another as a part of the carbon cycle.

Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.

Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.

Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. Some is buried and will become fossil fuels in millions and millions of years.

Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration.

Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels. Of this massive amount, 3.3 billion tons stays in the atmosphere. Most of the remainder becomes dissolved in seawater.

Carbon moves from the atmosphere to the oceans. The oceans, and other bodies of water, absorb some carbon from the atmosphere. The carbon is dissolved into the water.

Carbon dioxide is a greenhouse gas and traps heat in the atmosphere. Without it and other greenhouse gases, Earth would be a frozen world. But since the start of the Industrial Revolution about 150 years ago humans have burned so much fuel and released so much carbon dioxide into the air that global climate has risen over one degree Fahrenheit. The atmosphere has not held this much carbon for at least 420,000 years according to data from ice cores. The recent increase in amounts of greenhouse gases such as carbon dioxide is having a significant impact on the warming of our planet.

The statement "According to urban anomie theory, the impersonal nature of city life extends to situations that do not call for social involvement" is true, as urban anomie theory suggests that the impersonal nature of city life leads to the breakdown of social bonds.

According to this theory, the fast pace of urban life, the diversity of populations, and the emphasis on individual achievement can lead to a weakening of social ties and a breakdown of social norms and values. As a result, individuals may feel disconnected from others and from society as a whole, leading to a sense of alienation and a lack of meaning in their lives. This sense of normlessness and detachment can extend beyond situations that require social involvement, such as interactions with neighbors or participation in community events, to other aspects of daily life.

Hence, the statement "According to urban anomie theory, the impersonal nature of city life extends to situations that do not call for social involvement" is true.

Answer:

It’s D ,I got it right on USAtestprep

Explanation:

The correct option for this answer is D, which signifies that the radioactivity will be highest in the Golgi apparatus, as proteins made on the rough endoplasmic reticulum are transported to the packaging center prior to leaving the cell.

Radioactivity may be defined as a spontaneous process that involves the emission of radiation in the form of particles or high-energy photons resulting from a nuclear reaction.

The path of protein transport determines the level of radioactivity in this experiment.

First, the radioactivity is found highest in the ribosomes of ER, then the proteins are transported to the region of the Golgi apparatus by an anograde pathway and reflect in radioactivity.

Therefore, it is well described above.

Explanation:

Reproduction is important in plants to produce their progeny and to maintain its population. Plant reproduction helps to maintain its birth rate and sustain the ecosystem. Reproduction helps to acquire new variations and adapt to the environment with the most desirable characters.

According to the gene interaction that is operating in the trait determination, the phenotypic ratios of the progeny produced when test-crossing a dihybrid are: a) 4:12, b) 8:8, and c) 12:4

-------------------------

To answer these questions, the first thing you should notice by looking at the phenotypic ratios provided, is that there are two genes involved in the trait, and there is interaction between them.

Let us assume diallelic genes. A and B are the dominant alleles, while a and b are the recessive alleles.

In the three cases (a, b, and c), F1 individuals are dihybrid. Their genotype is AaBb.

Observing the altered phenotype proportions of the offspring can reveal which interaction is operating in the trait determination.

We can use the phenotypic ratio to determine the interaction, so:

When talking about epistasis, we are referring to an interruption.

The epistatic gene can alter, influence, or suppress the expression of a hypostatic gene.

In Duplicate gene action, there are two genes involved in the expression of a phenotype, and the presence of at least one dominant allele is enough to produce the dominant phenotype. Phenotypic ratio 15:1.

So now, let us make the test-cross.

Note: You will see that the cross is the same in the three cases, but the phenotypic ratio changes according to the interaction.

Cross) dihybrid individual with h0m0zyg0us recessive one

Parental)           AaBb            x          aabb

Gametes)  AB, Ab, aB, ab             ab, ab, ab, ab

Punnett square)     AB            Ab            aB            ab

                 ab       AaBb        Aabb        aaBb        aabb

                 ab       AaBb        Aabb        aaBb        aabb  

                 ab       AaBb        Aabb        aaBb        aabb

                 ab       AaBb        Aabb        aaBb        aabb

F2) Phenotypic ratio

***Double recessive epistasis  ⇒  4:12

Both genes in recessive state inhibit the expression of the trait.

***Recessive epistasis  ⇒  8:8

In h0m0zyg0us recessive state, Gene A inhibits the expression of B.

***Duplicate gene action   ⇒  12:4

Only one dominant allele, either A or B, is enough to express the trait.

Phenotypic ratios:

a) 4:12 = 1:3

b) 8:8 = 1:1

c) 12:4 = 3:1
