b. beginning of sperm production
c. beards grow thicker and their voices become slightly deeper and richer
d. increased body hair begins

Answers

Answer 1

Answer:

A

Explanation:

Answer 2

Answer:

c. beards grow thicker and their voices become slightly deeper and richer

Explanation:

Early adulthood scientifically lasts from age 20 to age 39, so, while you may be thinking puberty (hair growth, etc) it is more subtle changes such as the fact that the voice 'become slightly deeper and richer' . Both males and females continue to put on more weight (hormonal, not dietary!). Hope this helps! :)

Pls, Hurry up? True or False + Explain. "Sea anemones are sessile organisms and stay permanently attached to their substrate."

Answers

Answer:

True

Explanation:

Sea anemones are one of the numerous predating animals found in the marine environment. They have cylindrical bodies whose bases are usually found attached to substrates and are therefore described as being sessile. However, a few species of sea anemones are known to be free swimmers.

Generally, sessile organisms are those that live their life attached to a substrate and, therefore, are not able to freely move about.

Answer:

True

Explanation:

This is because sea anemone polyp is permanently attached to the beneath of the base where it stay by it base called pedal foot. It sometimes glide around in order to prevent itself from predation and it uses it's tentacle to catch moving food particles around it and consume it. It belong to the group cnidaria.

2. "Natural selection is usually thought of as an agent of change in populations, but it can also act to maintain the status quo."
In a short, written response, analyze and evaluate this statement. Include the range of responses of a population to changes in the environment, such as differential reproductive success, the adaptation and development of diversity in and among species, and the change in populations.

Answers

Answer:

Those organisms survive and maintain its population who are chosen by natural selection.

Explanation:

This statement means that when the population experiences a new set of environmental conditions, two things are happened i. e. the population either adjusts through natural selection or becomes extinct. The fossil of dinosaur indicates that extinction occur due to changed in the environment. If the population made changes in itself and adapt the environment then the organism survive otherwise extinction occur.

Answers

Answer:

False.

Explanation:

All of the things found in the Earth system can be categorized into four (4) main categories and these includes;

I. Land: this subsystem forms a sphere which is generally referred to as litosphere.

II. Water: this subsystem forms a sphere which is generally referred to as hydrosphere. It comprises of landforms such as mountains, valleys, plateaus, ridge, rocks, etc.

III. Air: this subsystem forms a sphere which is generally referred to as atmosphere. This sphere comprises of gases such as oxygen, carbon dioxide, nitrogen, etc.

IV. Living organisms: this subsystem forms a sphere which is generally referred to as biosphere. It comprises of all living things such as humans, animals and plants.

If humans change the function or equilibrium of one of Earth's systems, this will significantly change the function or equilibrium of all of Earth's systems. Consequently, these changes result in environmental phenomenon such as volcanoes, earthquakes, tornadoes, wildfire, etc.

An experiment, or experimental research, is a research method in which the researcher manipulates or changes the value of one variable, (the independent variable) and measures the variable that is considered the dependent variable, in order to find how the change affects it.

The other three posible answers, observational research, survey and case study are also research methods, but the researcher can't manipulate or control any of the variables, these methods are used only to measure a specific variable.

The ability to curl the tongue in dominant to the inability to do so. If Eric (heterozygous tongue curler) marries Brandy (also heterozygous) what are the predicted GTs and PTs of the offspring?

Answers

Answer:

Genotype = 1CC: 2Cc: 1cc

Phenotype = 3 tongue curler : 1 non-tongue curler

Explanation:

This question involves a single gene that codes for the ability or not to curl the tongue. The ability to curl the tongue (C) is dominant to the inability to do so (c). This means that a heterozygote will be able to curl his/her tongue.

According to this question, If Eric, who is a heterozygous tongue curler (Cc) marries Brandy who is also heterozygous (Cc) i.e. Cc × Cc, the following gametes will be produced by each parent: C and c.

Using these gametes in a punnet square (see attached image), the predicted genotype of the offspring is 1CC: 2Cc: 1cc while the predicted phenotype is 3 tongue curler : 1 non-tongue curler.

What is on a transplanted organ that causes the transplant recipient's body to reject it?

Answers

Answer:

Major histocompatibility complex (MHC) antigens

Explanation:

The process in which recipient body rejects the transplanted organ is called a allograft rejection or transplantation rejection.

A transplanted organ contains Major histocompatibility complex (MHC) antigens which are required to be accepted by the recipient's body to function properly but T cells in recipient's body become alloreactive and recognize MHC antigens (donor-derived antigens) as foreign and starts making antibodies against it. Which means the recipient's body is rejecting the  transplanted organ.

Hence, the correct answer is "Major histocompatibility complex (MHC) antigens".

What is free nitrogen? Nitrogen gas is called "free" nitrogen, meaning it is not combined with other kinds of atoms. Most organisms can use nitrogen only once it has been "fixed," or combined with other elements to form nitrogen-containing compounds.

Answers

Answer:

About 78% of the Earth's atmosphere is made up of "free" nitrogen (N2), produced by biological and chemical processes within the biosphere and not combined with other elements. ... One family of nitrogen compounds produced by nitrogen - fixing bacteria are called nitrates.

Explanation:

Hope this helps

Free nitrogen refers to nitrogen gas (N₂) that exists in the Earth's atmosphere as a diatomic molecule consisting of two nitrogen atoms bonded together. It is called "free" nitrogen because it is not chemically combined with other elements or atoms.

Nitrogen gas makes up approximately 78% of the Earth's atmosphere, making it the most abundant gas present. Despite its abundance, most organisms cannot directly utilize nitrogen gas in this form. This is because the bond between the two nitrogen atoms is very strong, requiring a significant amount of energy to break.

Therefore, free nitrogen refers to nitrogen gas (N₂) present in the atmosphere that is not chemically combined with other elements. It needs to undergo nitrogen fixation to be converted into usable forms before most organisms can utilize it.
