Answer:
A) Chromosomes are made of DNA
C) Alleles are the different forms of a gene that can exist
D) Chromosomes contain genes that control the inheritance of traits.
Explanation:
Chromosomes are long molecules of deoxyribonucleic acid (DNA) that contain part (or all) of the genetic material of an organism. Humans contain 46 chromosomes organized in 23 pairs of homologous chromosomes (22 pairs of autosomal chromosomes and one pair of sex chromosomes, X and Y). Moreover, a gene is a physical segment of a chromosome that contains the information to encode a protein. Alleles are different forms of a gene (i.e., gene variants) that may be caused by mutations or genetic recombination. Humans are diploid organisms (2N: 46), and therefore we have two copies of each gene (alleles), one on each homologous chromosome.
What is one major difference between viruses and bacteria?
A Viruses can make you sick; bacteria can't
B Viruses can be neutralized by stomach acids; bacteria can't
C Bacteria can be treated with antibiotics; viruses can't
D Bacteria can cause infections; viruses can't
Answer:
C. Bacteria can be treated with antibiotics; viruses can't
Explanation:
Antibiotics are meant to kill living pathogens. They don't work on viruses because viruses aren't actually alive, per se.

Can two different species of fungi from two different genus' mutate into a new species? i just want to know if it's a possibility, and how gigantic or slim the chances are of it happening.
Answer:
Yes, it is possible.
Explanation:
In this case, I'm guessing you mean breeding.
If that's the case, they will form hybrids.
Between two different species, inter specific hybrids will be formed.
Between two different genus, intergeneric hybrids will be formed.
There's even rare cases of breeding between two families.
So while it is possible for different species and/or genus to breed and form new species, in interspecific breeding for instance, they will have features similar to the parents but turn out sterile.
So to answer your question, it is possible.

How is antibiotic resistance related to natural selection?
Answer:
Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.

How does the lipid portion help maintain water concentration on each side of the bilateral?
Answer:
Explanation:The phospholipid bilayer formed by these interactions makes a good barrier between the interior and exterior of the cell, because water and other polar or charged substances cannot easily cross the hydrophobic core of the membrane. Can water cross the plasma membrane at all?
It also helps the cell move things in and out. The cell membrane is made of what is called a phospholipid bilayer, which means it has two layers of phospholipids. ... This allows the phosphates to be exposed to water, either in the cell or the environment, while the lipids are protected from water Lipids are essential for all life on Earth. They play many important roles in maintaining the health of an organism. Arguably the most important function lipids perform is as the building blocks of cellular membranes. Other functions include energy storage, insulation, cellular communication and protection.Large quantities of water molecules constantly move across cell membranes by simple diffusion, often facilitated by movement through membrane proteins, including aquaporins. In general, net movement of water into or out of cells is negligible.

4. What best describes the role of mutations in evolution?
a. Mutations are not necessary for evolution because they are not herita
b. Mutations are useful for evolution to occur because they promote ger
uniformity within a population.
c. Mutations are essential for evolution to occur because they produce
variations within a population.
d. Mutations are essential for evolution to occur because they are respo
environmental changes.
Answer: option C.
Mutations are essential for evolution to occur because they produce variations within a population.
Explanation:
This is because Mutation refer to change in the genetic content or DNA composition of organisms. Therefore , for evolution to occur there must be Mutation because it is the main source of genetic variation or causes genetic variation needed for evolution.
Mutation is important as the basics of evolution because it produce a new DNA sequence for a gene function, which lead to the formation of new allele.
Which of the following describes how Earth's atmosphere changed during Precambrian time?
A. The amount of carbon dioxide increased.
B. Torrential rains never reached the surface until the Paleozoic era.
C. The amount of oxygen increased.
D. Precambrian oxygen was quickly used up by plants.
Answer:
c
Explanation:
During Precambrian time, The amount of oxygen increased in the earth's atmosphere. Therefore, option C is correct.
What is the Precambrian time period?From roughly 4.6 billion years ago, when Earth first started to form, to the start of the Cambrian Period, 541 million years ago, is the Precambrian Period. It is the earliest era which is followed by the Cambrian period.
Large objects bombarded the Precambrian Earth, the crust was split into the first continents and ocean basins, crustal plates were mobilized, the atmosphere changed from reducing to oxidizing, and early life began and evolved. Climate and geologic events are responsible for the end of this period.
During this period, the amount of oxygen increased rapidly. Therefore, option C is correct.

& Milk wood plants are essential for monarch butterfly survival. The butterflies drink the nectar from milkweed
flowers. The female monarchs lay their eggs only on milkweed plants, and the monarch caterpillars rely on the
milleweed plant as its primary food source. Milkweed produces a poisonous toxin that the caterpillars are able to
collect in specialized sacs, which in turn makes the caterpillars poisonous to predators. Milkweed plants are
pollinated by monarch butterflies as well as other insects. Which of the following best describes the resulting
daptations found in milkweed plants and monarch butterflies?

Answer:
Coevolution
Explanation:
There is a symbiotic relationship between them because the plants get pollinated and the butterflies get protection. Their relationship can also be described by the term mutualism.

Why do we need friction in our world?
Friction is a force that works against motion. While walking, friction helps us maintain our stability and prevents us from slipping. Friction also works the same way with cars and vehicles in general, preventing them from skidding and helping them stop when the brakes are applied. We also need friction to make a fire.
Without friction between the shoes and the ground, you cannot walk properly. If there is no friction, all of us would be sliding around without any control over ourselves. While walking, you're pushing your foot back as you try to step forward. Friction holds your shoe to the ground so you can walk around.

What makes one animal more adapted than another?
1. It has acclimatized to its environment during its lifetime.
2. Its phenotype is better suited to its environment.
3. It is more fit, regardless of environment.
4. It will live longer than most other individuals.
Answer:
The answer is 2. its phenotype is better suited to its environment.
Explanation:
Adaptation is the process by which animals pass on genes that make their offspring increasingly better at surviving and reproducing in their given environment. and also I took the quiz.
Its phenotype is better suited to its environment," is generally the most significant factor. Therefore, option (2) is correct.
What is adaptation?Adaptation is a biological process by which a population of organisms becomes better suited to its environment over time. This process involves changes in an organism's behavioral, anatomical, or physiological traits that enable it to survive and reproduce in its environment.
Adaptations may be the result of natural selection, where certain traits that confer an advantage in the environment are passed on to offspring, leading to evolutionary changes in the population. Adaptations can be observed at different levels, from the molecular to the ecosystem, and they are crucial for the survival and success of species in their environments.
