Answer:
if the disease kills all the seaguells then it will affect the food chain negativleyy because the population of the species that would eat them (predator) will decrease dramatically and the fish ( what the seaguells eat ) there peopulation will increase dramatically because they are not being eaten .
Explanation:
hope this helps , sorry middle school was a long time ago for me : )
Answer and explanation: it would mean that there would be an increase of fish which is what seaguls eat but a decrease of, for example, leopard seals because if there aren't enough seagulls the leopard seals would die of starvation which would then again decrease another animal species because there aren't enough leopard seals. This would then repeat itself again and again.

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

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.

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.

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.

how does the virus use a host cell to make copies of itself
Answer:
I wasn't quite sure what virus you were referring to in your question, but here's a general answer: Viruses use their host cells' machinery to replicate themselves.
If they are a specific type of virus known as a retrovirus, they have the ability to use the host cells' enzymes to change the RNA contained within the virus into DNA (via some type of replication I suppose).
In other cases, if they contain DNA instead of RNA (that is, the virus), they can use the host cell's machinery to create RNA via enzymes involved in transcription and/or they can incorporate that DNA into the host cell's DNA. This is part of a type of viral replication cycle known as the lysogenic cycle.
In another type of viral replication cycle known as the lytic cycle, the virus simply has itself and its genome duplicated until the host cell bursts, releasing the viral material. Here, again, the virus uses the host cell's machinery to replicate itself.

During daylight savings, Christie's neighborhood soccer games get cut short because the sky becomes dark much earlier than during the summer. Her father talked to the electric company about installing large lights above the field so Christie and other kids in the community could continue their soccer games after dark. The electric company informed Christie's father that although the light poles could be installed, there are too many short trees and trees with low branches in the park to connect electrical lines. Without electricity delivered to the light poles, they would not work. Christie and her father talked about this information with neighborhood residents and together they came up with several ways to solve the problem.
Considering the concerns of everyone involved, which idea would be the BEST solution to the problem?
A)
Instead of electrical light poles, install solar-powered light poles.
B)
Parents can leave their cars running with headlights on facing the park.
Build several large fire pits around the field and light them each night.
D)
Cut down the larger trees, install the electrical lines, and replant the area
with shrubs.

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.

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.
