What is evolution?Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction.
Moreover, evolution reflects the adaptations of organisms to their changing environments and can result in altered genes, novel traits, and new species.
Hence, evolutionary processes depend on both changes in genetic variability and changes in allele frequencies over time.

A symbiotic relationship in which one species benefits and the other is harmed is known as mutualism. predation. commensalism. parasitism.
Answer:
Parasitism
Explanation:
Example: Mosquitoes feed off the blood of a human and is benefitted, the human is harmed because the mosquitoe exposed he/she to malaria.
A symbiotic relationship in which one species benefits and the other is harmed is called parasitism. The parasite lives on the food of the host. Fourth option is correct.
What are different types of symbiotic associations?In symbiosis, two organisms are present in close contact. There are different types of relationships seen in nature, such as mutualism, commensalism, parasitism, etc.
Mutualism occurs when two organisms, such as lichen, benefit from one another. Lichen is an association of algae and fungi. Algae makes food that is consumed by fungi, and fungi provide algae for a place to live.
In parasitism, one is the host, and the other is the parasite. An example is the tapeworm in the human intestine. Tape worms consume digested human food and harm humans by spreading their population. Here, the host is negatively impacted by the presence of parasites.
In predation, both are harmed as both are involved in the fighting. In commensalism, one party gets benefits while the other is not harmed by the association.
Hence, the fourth option is the correct answer, which is parasitism.

what atoms makeup sugar molecules, amino acids, and fatty acids?
what do you notice about the atoms that make up these molecules?
how are these atoms used to make new molecules? what types of molecules are made?
where does the energy come from to produce these new molecules?
Answer:
In chemical digestion, enzymes break down food into the small molecules the body can use. It is important to break down macromolecules into smaller fragments that are of suitable size for absorption across cell membranes.
Amino acids are the monomers that makes up protein
If it's in the table, it's an element! Atoms can join together - they form bonds together - to make MOLECULES. For example, two atoms of hydrogen hook together to form a molecule of hydrogen, H2 for short.
BONDING. When atoms join together to form molecules, they are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons between the atoms. ... Different atoms use these electrons to form one of three different types of bond: ionic bonds, covalent bonds, or metallic bonds.

Photophores help the animals which zone of the ocean? How do they help?
Question 6 options:
coasts - tentacles to attach to rocks
frozen ocean areas - help blood from freezing
deep sea areas - attract prey with light
coral reef areas - calcification for skeletal protection
Answer:
Deep Sea Areas
Explanation:
Photophores are animals that produce light.
Photophores help the animals in deep sea areas—attract prey with light of the ocean. Therefore, the correct option is C.
What are photophores?Deep sea animals live in complete darkness where no sunlight can penetrate. In order to find food or mates, many of these animals have evolved special light-producing organs called photophores. These organs emit light, which can be used to attract prey or to communicate with other members of the same species.
The light produced by photophores can vary in color, brightness, and pattern depending on the species. Some animals use their photophores to create a dazzling display that confuses or disorients their predators, while others use them to mimic the appearance of other animals or objects in their environment. Therefore, the correct option is C.

What happens to the blood pressure when the blood vessels get longer?
Answer:
:)
Explanation:
The main artery from the heart (aorta) becomes thicker, stiffer, and less flexible. This is probably related to changes in the connective tissue of the blood vessel wall. This makes the blood pressure higher and makes the heart work harder, which may lead to thickening of the heart muscle (hypertrophy).
. Does the employee ever seem defensive during this discussion? How successful is her defensive reaction?
Hello. You did not reveal the discussion to which this question refers, which makes it impossible for this question to be answered. However, I will try to help you in the best possible way.
To find out if the employee remains in defensive behavior during an argument, you need to look at how that employee is positioning himself. Defensive behavior is one where the individual, at all times, tries to preserve his self-image and protect himself from possible accusations, even if it is necessary to distort situations. If the employee exhibits this behavior at the time the discussion takes place, it is because he is taking a defensive position. This behavior is successful when the employee is able to preserve his reputation at the end of the discussion.

Choose the mutation that you think has caused Calix’s calico fur coloring. Form a hypothesis to explain your reasoning. You will be able to revise your hypothesis as you collect more data. ( Ya'll i need a hypothesis )
The complete question is as follows:
Hypothesis Cas More Information: Here is a summary of the data, Mass of DNA Cat Res per Coll Mother Father Calix 1520 fg 1495 fg 1535 fg . The mass of an X chromosome is 40 fg. • Point mutations do not change the mass of DNA. • In chromosomal rearrangement, some daughter cells gain parts of chromosomes and some lose parts of chromosomes. • In nondisjunction, daughter cells gain a whole entire chromosome. Obe Exp Нур 는 Exp Point Mutation in Melosis Chromosomal Rearrangement Nondisjunction Choose the mutation that you think has caused Calix's calico fur coloring. Form a hypothesis to explain your reasoning. You will be able to revise your hypothesis as you collect more data.
Answer:
The correct answer is - non-disjunction.
Explanation:
Calix's calico has an X chromosome gene that determines the color of fur. One allele forms orange fur and the other give rise to black. In heterozygous give rise to orange patches on black.
Mother has autosome and 2-X chromosomes.
Mass of 2 X chromosomes will be
= 40*2
= 80fg
So mass of autosomes = 1520-80
= 1440fg
Mass of sex chromosomes in father is = 1495-1440
= 55fg
So the mass of Y=55-40
= 15fg
It is clear that the mass of DNA of Calix is exactly 15 more than DNA of the mother. So we can say that Calix has an entire Y chromosome in extra.
So the answer is non-disjunction.
The right option is - non-disjunction.
Information regarding Calix’s calico:It comprises of X chromosome gene that measured the fur color. In the case of heterozygous, it provides the increment with respect to orange that patches on black.
Since Mother has autosome and 2-X chromosomes.
So,
Mass of 2 X chromosomes should be
= 40*2
= 80fg
Now
The mass of autosomes should be
= 1520 - 80
= 1440fg
Now
Mass of s-ex chromosomes in father should be
= 1495-1440
= 55fg
Now finally the mass of Y is
= 55 - 40
= 15fg
Based on the above calculation, the mass of DNA of Calix should be 15 i.e. more than the DNA of the mother.

at what point did the climate began to fluctuate more severely ? (2 points )
Answer:
Due to greenhouse gases.
Explanation:
When the high emission of greenhouse gases occurs, the climate began to fluctuate more severely because greenhouse gases such as carbondioxide gas and methane etc block the solar radiation that is reflected back to space which is responsible for the change of climate. If there is more greenhouse gases are emitted in the atmosphere so there is more fluctuation in the climatic condition of earth atmosphere so we can conclude that greenhouse gases leads to fluctuation of climatic conditions more severely..

Complete the table below to show the difference between active and passive transport. Put a “X” in boxes that satisfy the statement.
Answer:
Active transport:
requires energymolecules move from low to high concentration sidesNa+ and K+ move by active transportSimple diffusion:
molecules move from high to low concentration sidesmolecules pass between lipids small non-polar and polar moleculesFacilitated diffusion:
molecules move from high to low concentration sidesinvolves channel proteinsmove large moleculesExplanation:
Simple Diffusion is the pathway of only small molecules that freely move through the membrane by momentary openings produced by the lipids' movements. Diffusion is a slow process that requires short distances and pronounced concentration gradients to be efficient. An example of diffusion is osmosis by which water is the transported molecule. Facilitated diffusion is the transport of hydrophilic molecules that can not freely cross the membrane. Channel protein and many carrier proteins are in charge of this transport. When uncharged molecules cross the membrane, they do it according to their concentration gradients, going from the more concentrated side to the lower concentrated one. When ions need to cross the membrane, the process depends on an electrochemical gradient. Glucose is an example of a hydrophilic protein that gets into the cell by facilitated diffusion.Simple diffusion and facilitated diffusion are both passive transport processes because they only depend on electrochemical gradients, so they do not need any energy to occur.
Active transport is the transport of molecules that move against the electrochemical gradient, so it does need energy to happen. Molecules move from the lower concentration side to the higher concentration side of the membrane. Carrier proteins are in charge of active transport. The needed energy might proceed from the ATP molecules or the membrane's electric potential. An example of molecules moved by active transport are the Na and K.In Active transport, molecules or ions move against the concentration gradient by using energy from ATP.
What is Membrane transport?The transfer of molecules across the plasma membrane into or out of the cell.
There are two types of membrane transport,
1. Passive transport:
When molecules move along the gradient. It can be of two types,
Simple diffusion (via phospholipids)Facilitated diffusion (via channel protein)2. Active transport:
When molecules move against the concentration gradient, they require energy. Energy is given by ATP.
Therefore, in Active transport, molecules or ions move against the concentration gradient by using energy from ATP.
