Answer:
ORGAN
Explanation:
The liver is a very important organ in the system of multicellular organisms e.g humans. It performs various functions in the body e.g. detoxification, metabolism etc. As rightly said in this question, multicellular organisms are made up of five levels of organization.
Firstly, all living organisms are made up of CELLS, which are the basic unit of life. Cells come together to form the TISSUE. Tissues that perform similar functions come together to form the ORGAN, the organ that specifically play a similar role in the body are collectively called ORGAN SYSTEM. The various organ systems make up the whole ORGANISM.
In this five level of organization, the liver falls under the ORGAN category because it is made up of cells called Hepatocytes, which come together to form tissues. The tissues collectively make up the LIVER.

The Hardy-Weinberg equation shows the frequencies of 100 percent of the alleles for a specific gene in a population.
If biologists can show that either p or q is changing over a period of time, what is occurring in the population?
The population is evolving.
The population is decreasing in size.
The population is stabilizing.
The population is not evolving.
Answer: I believe that the answer is that the population is evolving
Explanation: I hope that this helps
In Hardy-Weinberg equation, If biologists can show that either p or q is changing over a period of time, the population is decreasing in size.
What do you mean by Hardy-Weinberg equilibrium?The Hardy–Weinberg principle, also known as the Hardy–Weinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a population will remain constant from generation to generation.
The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.
For populations in the Hardy-Weinberg equilibrium, the equation connects allele frequencies to genotype frequencies. This equation allows us to compare a population's genetic structure in reality over time to the expected genetic structure.

How does the endocrine system affect the excretory system?
A. It sends messages using hormones.
B. It allows oxygen to diffuse across membranes.
C. It sends messages along action potentials.
O D. It produces digestive enzymes.
SUBMIT
Answer:
Option A
Explanation:
The endocrine system and the excretory system works hand in hand in maintained thé functions of the body and in this context that kidneys. The hypothalamus functions in monitoring the amount of electrolytes in the blood and an increase in this amount indicates dehydration among others, whose cause might be s a result of low water intake, too much sweat etc. Detecting this, the hypothalamus signals for the secretion of antidiuretic hormone which moves to the kidneys and stimulate the organ to reabsorb more water. This hormone is transferred to and released by the pituitary gland all these being part of the endocrine system.

What are some examples of comparative embryology in evolution?
Answer:
Similarities in structure among distantly related species are analogous if they evolved independently in similar environments. They provide good evidence for natural selection. Examples of evidence from embryology which supports common ancestry include the tail and gill slits present in all early vertebrate embryos.

If there are 10 chromosomes in a particular cell at the start of prophase how many will be present in the same cell at the end of anaphase. Before cytokinesis has begun? Hint: first of all, state the number of chromosomes. Then explain why you think so.
Answer:
20 chromosomes
Explanation:
Mitosis is a kind of cell division that results in daughter cells with same number of chromosomes as the parent cell. It involves stages including Prophase, Metaphase, Anaphase and Telophase. In prophase, the Chromatin condenses into Chromosomes.
In Anaphase stage, the 10 chromosomes as mentioned in the question divides into opposite poles of the cell. One individual chromosome contains two sister chromatids, which actually separates in the Anaphase stage. Hence, at the end of the Anaphase stage, there will be 10 chromatids each at opposite poles of the cell. Each chromatid at this stage is considered a chromosome.
Hence, a cell with 10 chromosomes will contain 20 chromosomes (10+10 chromatids on each pole) in the Anaphase stage just before the cell divides into two in a process called CYTOKINESIS.

The system in the body which carries information from the glands and organs to brain is endocrine system.
What is endocrine system?
All mammals, birds, fish, and many other forms of living things have endocrine systems, commonly known as hormone systems. They are composed of:
Throughout the body, there are glands; hormones that are produced by the glands and released into the bloodstream or the fluid around cells; and receptors in various organs and tissues that detect the hormones and react to them.
All bodily components are affected by hormones, but only target cells with the right receptors can react. In both humans and other vertebrates, more than 50 hormones have been discovered.
Therefore, The system in the body which carries information from the glands and organs to brain is endocrine system.

Which is part of the theory of evolution by natural selection?
A. All animals in a population are able to reproduce.
B. Animals have no variation among themselves.
C. Adaptations cannot be passed along to later generations.
D. Small changes add up over many generations.
Answer:
D. Small changes add up over many generations.
Explanation:
It's not A because not all animals in a population can always reproduce. Some may be infertile.
It's not B because genetic variety is something that occurs naturally. Because of genetic variety, random mutations can occur (these mutations later become adaptations).
It's not C because adaptations can be passed down to later generations. These adaptations can lead to natural selection which eventually leads to evolution.

A student made a model of an onion skin cell she viewed using a microscope. The scale is 1:500.The students cell model has a length of 15cm. How many centimeters is the real cells length?
Answer:
Length of the real cells = 7500 cm
Explanation:
A scale model is a physical representation of an object that has the same aspects as that of the object.
A scale model can be used in fields like engineering, film making, salesmanship, etc
Length of the student's cell model = 15 cm
The scale is [tex]1:500[/tex]
So,
Length of the student's cell model / Length of the real cells = [tex]1:500[/tex]
15 / Length of the real cells = [tex]1:500[/tex]
Length of the real cells = 15 × 500 = 7500 cm
Answer:
7500 cm

What is the best way to help them decide if the information is true?
Answer:
I think the answer is C.
Explanation:
The best way to help them to decide about the information of the scenario is that they can use reliable web sites or books to get more information. The correct option is C.
What are reliable information?Reliable information or data is accurate or trustworthy: Broker-dealers must use their discretion when determining whether issuer information is reliable.
Trustworthy information/data/evidence currently, investors do not always have timely access to reliable information.
Reliable data must come from trustworthy sources. A reliable source will provide a "thorough, well-reasoned theory, argument, etc. based on strong evidence," according to UGA Libraries.
Scholarly, peer-reviewed articles and books are examples of highly credible sources.
Recognizing the type (genre) of knowledge you are going to encounter allows you to predict its form, function, and context, making what you find more understandable and assisting you in determining the information's relevance and validity.

Answer:
Bat boxes at homes provide housing to insect-eating bats which has two major positive effects on the environment:
Bat boxes provide bats a natural habitat and they act as natural pest control in the environment. They are very helpful for reducing or controlling the population of mosquito and balance the food chain in the environment.Bat is known as very good pollinators which helps in the pollination of flowers or spread their seeds. So bat boxes at home increase pollination in nearby areas and increase biodiversity in the environment.Hence, bat boxes at houses have a positive effect on the environment.
