Answer:
Driving or using cars as a method of transportation increases the amount of Co2 released into the atmosphere. Due to this the environment becomes less and less unstable. Another daily thing I do every day that effects the environment is throwing away trash. As our trash fills the landfills some of them can be picked up by birds or even end up getting blown into the ocean. However, recycling is one positive aspect in our every day lives. When we recycle companies and factories are able to reuse things we no longer use. Because of this we are able to protect many ecosystems and the environment.
Cells in the body use oxygen
for cellular respiration. Which is the result of cellular respiration?
ATP is produced, and carbon dioxide (CO2) is released.
ATP is consumed, and carbon dioxide (CO2) is released.
ATP is consumed, and carbon dioxide (CO2) is absorbed.
ATP is produced, and carbon dioxide (CO) is absorbed.
Answer:
A
Explanation:
Cellular respiration is done in the mitochondria, the powerhouse of the cell. Their job is to create ATP, and that eliminates B and C. Carbon dioxide is created as waste, then its released that is why we breathe OUT CO2

plz help!!!!!!!! A natural biological cooling process is sweating. Using your knowledge of endothermic and exothermic, explain why your body feels cooler when it sweats.
Answer and Explanation:
An exothermic reaction takes place when heat flows out of a system into its surroundings. ... When you sweat, the system – your body – cools down as perspiration evaporates from the skin and heat flows to the surrounding area. This means sweating is an exothermic reaction.
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.

BIOLOGY EXPERTS!!!! Shared core processes support the relatedness of all eukaryotes. Discuss how chromosome structure and function provides insights into the history of life on Earth.
Answer: Many eukaryotic organisms are related based on the shared core characteristics and processes.
Explanation:
The following are the shared core processes shared by all eukaryotes.:
1. Cytoskeleton: It is a network of structural proteins, that helps in movement of cell and organelle support.
2. Membrane-bound organelle: Mitochondria and chloroplast are organelles that formed via endosymbiosis these are present in all eukaryotic organisms.
The DNA is the basic genetic material that is found in almost majority of living beings on earth. The DNA is being transmitted from the primitive organisms on earth to the modern day organisms. The chromosomes are the carriers of DNA. These chromosomes are passed from the parents to the offsprings through reproduction. This is the basis of relatedness among organisms and these are also considered while studying the phylogenetic relationships.

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.

FROM THE LUNGS, BLOOD COMES BACK TO THE HEART. DESCRIBE THE PATH THIS BLOOD FOLLOWS UNTIL IT ENTERS THE AORTA.
Answer:
Tricuspid valve is the path of blood through the heart and lungs
Explanation:
Blood is also responsible for transiting the blood and nutrients. The blood reached right atrium and from here it reached the right ventricles with the help of tricuspid valve. When the ventricles are full it closes to stop blood from going back to the atrium.
The inferior and the superior vena cava let the blood enter through them. The heart left the blood with the help of pulmonary valve to the pulmonary artery and the blood reached the lungs.

A. How long are the insect's antennae?
B. Are the insect's antennae longer than its head?
C. Are the insect's antennae long or short?
D. How does the insect use its antennae?
Answer:
B. Are the insect’s antennae longer than its head?
Explanation:
Dichotomous key refers to the tool or method which helps the scientist to identify organisms.
It uses a specific series of questions which help in segregation of organisms and ultimately help the scientist to identify the organism on the basis of the observations or properties share by the organism.
Example of a simple dichotomous key is shown below.
Similarly, insects can have antennae longer or shorter than their heads. Thus, the question "Are the insect’s antennae longer than its head?" would help in segregating insects based on their antennae length.
happy to help ya:)
The statement B is correct. Are the insect’s antennae longer than its head?
What do you mean by dichotomous keys?A dichotomous key is an important scientific tool, used to identify different organisms, based the organism's observable traits. Dichotomous keys consist of a series of statements with two choices in each step that will lead users to the correct identification.
Moreover, for example, in tree identification, a dichotomous key might ask whether the tree has leaves or needles. The key then directs the user down one list of questions if the tree has leaves, and a different question list if it has needles.
Therefore, dichotomous keys are useful for biological classification as well as identification. The word dichotomous is derived from the Greek words meaning “two parts.” Each step in the key provides two contrasting choices about a characteristic.
