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.

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.

Many people place bat boxes on their property to provide housing that attracts insect -eating bats. Explain how this activity has a positive effect on the environment.
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.

VERY EASY QUESTION. WILL MARK BRAINLIEST When is the peak hurricane season for the Atlantic Ocean Basin, and why do hurricanes peak during this time? August to October, because ocean temperatures are the warmest around the equator at that time August to October, because the atmosphere is the driest around the equator at that time September to December, because the atmosphere is the driest around the equator at that time September to December, because ocean temperatures are the warmest around the equator at that time
Explanation:
When is the peak hurricane season for the Atlantic Ocean Basin?
The official hurricane season for the Atlantic Ocean Basin is from 1 June to 30 November.
Why do hurricanes peak during this time?
Although the Atlantic hurricane season officially began on June 1st, a roughly eight-week period that is often the most active and dangerous time for tropical cyclone activity.

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.
