Answer:
Mutations affect organisms in two different ways. Genetic mutations are inherited DNA changes that can be passed on to the next generation. Somatic mutations are DNA changes that are acquired after birth. Mutations can be helpful, harmful or make no difference at all.

Answer: Lactic acid
Explanation: The acid is caused by anaerobic respiration, which you do when you do not get enough oxygen
Where does the exchange of oxygen (from the air) with carbon dioxide (from the cells) take place?
A. Where are the bronchi meet the bronchioles
B. Where the blood meets the cells
C. Where the nasal passages meet the air
D. Where are the alveoli meet capillaries
Answer:
The Answer is Option D.
Exchange of respiratory gases, oxygen and carbon dioxide take place in the alveoli of the lungs. Oxygen which is inhaled from the atmosphere diffuses through the walls of the alveoli and reaches to the adjacent capillaries into the red blood cells.
Answer:
D. Where are the alveoli meet capillaries

What are fossil fuels? Why do you think they are used if they cause climate change?
Answer:
fossil fuels are natural fuels like coal.
When fossil fuels are burnt they release large amounts of carbon dioxide ( a greenhouse gas ) that traps heat in our atmosphere causing global warming which is also a factor of climate change

In two or three well-developed paragraphs, explain how citizens can affect environmental policy at each level of government: local, state, and national.
Local
Citizens can take a local initiative for example go around and voluntarily pick up trash and garbage make sure to spread the word to keep the environment safe and clean since us citizens are the ones who need to take action on the policies
State
State governments can introduces advantages for the citizens who take part in the policies and hold marches and events to raise awareness
National
National governments can introduce enticing policies for both citizens and state governments since we need everyone to take part
You are walking through a mixed evergreen-deciduous forest, where approximately 10 percent of the trees are eastern hemlocks, a species of evergreen tree that casts very deep shade on the forest understory. Interestingly, under every eastern hemlock, you find the same small herbaceous plant species. However, you never observe this species anywhere else, even though a healthy diversity of other species live throughout the forest understory. You expect the small herbaceous species to have _____ growth, _____ sexual maturity, _____ energy expended on seeds, and _____ reproduction. Please choose the correct answer from the following choices, and then select the submit answer button. Answer choices fast; early; high; no vegetative slow; late; low; vegetative slow; early; low; vegetative fast; early; low; vegetative slow; late; high; no vegetative
Answer: slow; late; low; vegetative
Explanation: Due to the casting of deep shade on the forest understory by eastern hemlock, direct sunlight and other necessities for photosynthesis and other life processes needed by the herbaceous plant species for optimum growth is being deprived.
However, coupled with the nature of these herbaceous plant species, having non-woody stems with their growth above the ground level often dieing off particularly in winter in the temperate zone, makes their growth in that kind of location to be stunted.
Thus, herbaceous plant species with slow growth rate leading to late sexual maturuty while having low expanded energy on seeds due to low photosynthetic rate and low vegetative reproduction should be expected.
Which of the following diseases can be cured using antibiotics?

C. Thyphoid
Explanation:
The molecule represented below is found in living things.
Which statement describes one characteristic of this molecule?
1.
It is the template for the replication of genetic information.
2.
Organic catalysts are made up of these molecules.
3.
It is different in each cell of an organism.
4.
Cell membranes contain many of these molecules.
The diagram of the molecule is attached with the answer.
Answer:
The correct answer is - 1. It is the template for the replication of genetic information.
Explanation:
The given molecule is a DNA molecule that is known as the molecule that takes genetic instructions in all living things and carries them to the next generation of cells.
The DNA molecule has two strands known as double helix formed by winding around one another, backbone of each strand has sugar (deoxyribose) and phosphate groups.
DNA plays a role of the template for the replication of the genetic information during DNA replication as well as transcription during protein synthesis.
4. What is the most likely explanation, if we see an increase over time
of a specific trait in a population?
Organisms with that trait are more suited to their environment or reproducing
Organisms without that new trait stopped reproducing.
The organisms without that trait either left or died off.
Organisms with that trait killed the organisms without the trait.

This fly has 14 chromosomes in its cells.7 maternal chromosomes and 7 paternal chromosomes.Assume you are a microscopist viewing this fly cells that are undergoing meiosis. Conclude the number of chromosomes/chromatids at the end of meiosis 1 as well at the end of meiosis 2
Answer:
23 pairs in meiosis 1 and 23 numbers in meiosis 2.
Explanation:
There are diploid number of chromosomes means double number of chromosomes at the end of meiosis 1 while on the other hand, at the end of meiosis 2, there are haploid number of chromosome means half number of chromosomes in each daughter cell. In humans meiosis 1, there are 23 pairs of chromosomes that is diploid in nature but in the end of meiosis 2, there are only 23 chromosomes in each daughter cell which is haploid in nature.

Which statement best explains why herbivores are not considered parasites
Answer:
Hello There!!
Explanation:
The answer is=>Parasite means that the organism must live inside (intracellular) or on the outside body of the organism (extracellular). The herbivores do not live on the host (plants) for its survival. They just eat the plants and fruits for getting energy. Therefore, the herbivores cannot be called as parasite.
