What is an event of a convention current in the air
Answer:
Convection drives the circulation of air in the earth’s atmosphere. The sun heats the air near the earth’s equator, which becomes less dense and rises upward. As it rises, it cools and becomes less dense than the air around it, spreading out and descending toward the equator again.

Which defensive adaptation would best help a plant survive in an environment with leaf-eating animals?
A.
large fruits
B.
thick stems
C.
sharp thorns
D. colorful flowers
Answer:
C. sharp thorns
Explanation:
The plants stand still, are not very physically active, and seem to be on the menu of many animals. Precisely because they cannot win at the first sign of danger, one has developed other ways in which they can defend themselves from annoying and dangerous animals.
Some have developed long thorns that repel attackers. Some have poisons that are very strong and because of which animals do not think of trying to eat that plant, but the defense of some plants seems to be well thought out and ready for all forms of attack.

What term describes parts of the body that are made from different kinds of cell
Answer:
The term that describes the parts of the body with different kindsof cells is organs, which in turn are made up of different tissues.
Explanation:
The cell is the structural and functional unit of all living beings, with the capacity to multiply and unite to form tissues.
Each tissue is a differentiated or specialized structure, formed by groups of cells of the same type, such as muscle, nerve, connective, cartilage and bone tissue, among others.
The specialized tissues in turn form organs, with specific structures and functions, such as muscle, brain and nerves or bones and joints. For this reason, organs are different body parts, formed by different kinds of cells.
True or False:
The immune system is designed to protect against pathogens such as microscopic organisms and foreign substances that arise from outside the body
Answer:
True.
Explanation:
Protecting against pathogens such as microscopic organisms and foreign substances that arise from outside the body is the role of the immune system.
Answer:
true
Explanation:
Inside your body there is an amazing protection mechanism called the immune system. It is designed to defend you against millions of bacteria, microbes, viruses, toxins and parasites that would love to invade your body. To understand the power of the immune system, all that you have to do is look at what happens to anything once it dies. That sounds gross, but it does show you something very important about your immune system.
When something dies, its immune system (along with everything else) shuts down. In a matter of hours, the body is invaded by all sorts of bacteria, microbes, parasites... None of these things are able to get in when your immune system is working, but the moment your immune system stops the door is wide open. Once you die it only takes a few weeks for these organisms to completely dismantle your body and carry it away, until all that's left is a skeleton. Obviously your immune system is doing something amazing to keep all of that dismantling from happening when you are alive.

Identify the types of point mutations depicted.
Answer:
The types of point mutation depicted are:
1. C. Silent mutation
2. B. Nonsense mutation
Explanation:
Point mutation is known to be a mutation that actually affects a single nucleotide and it has to do with the substitution of one base for another. This substitution can occur by changing, inserting or deleting a DNA or RNA sequence. A nonsense mutation refers to a change in DNA which leads a protein to either terminate or end its translation so quickly than expected. This mutation is commonly seen in humans.
Silent mutation is known to be the mutation in DNA whereby there are no effects which are observable in an organism's phenotype. This type of mutation are seen as a specific type of neutral mutation.

Answer:
According to the diagram, cell growth and preparation occur in steps 2 and 4, corresponding to phases G₁ and G₂ of cell cycle.
Explanation:
G₁ phase consists of the beginning of the cell cycle, following the process of previous division, and occurs in a cell that prepares for a next division. In this phase growth depends on the proliferation of mRNA to increase protein synthesis.
G₂ phase —third phase of the cycle— is the continuation of the process of cell growth induced by protein synthesis. Changes occur at the level of cellular components, as preparation of the cell prior to division.

Answer:
aluminum silicate minerals
Explanation:
Aluminum silicate minerals has the same chemical composition most similar to andalusite, sillimanite, and kyanite.
What is chemical composition?Chemical composition is defined as any substance made up of similar molecules made up of atoms from two or more chemical elements.
It can also be defined as a scientific symbol used to show the number and kind of atoms in a molecule.
Chemical composition containing basic components such as carbon, hydrogen, and oxygen which are very important for development and growth of human life.
Human body mainly consist of six important elements which help in growth and development. They are Carbon, oxygen, hydrogen, nitrogen, calcium and phosphate.

What characteristic of water causes water to stick to the side of a test tube?
I need a claim, evidence, and reasoning !
Answer:
The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity (Claim).
Explanation:
Water (H₂O) is a polar molecule with the ability to generate van der Waals forces, which is explained by the 4 hydrogen bonds it forms to bind to other substances. The consequence of the forces of the molecular bonds are four properties of H₂O, including surface tension, cohesion, adhesion and capillarity.
- Claim: The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity.
- Evidence: Cohesion and adhesion of water are properties that come from the forces of the molecular bonds of water, and whose effect is the ability of water to wet surfaces and adhere to a tube that contains it, the latter due to capillarity. Capillarity also allows water to rise through the roots and stems of plants, through their thin vascular ducts.
- Reasoning: cohesion in water depends on the force of attraction between H₂O molecules, adhesion is the capacity of H₂O molecules to join other different molecules and —together with surface tension— make H₂O molecules close to the walls of a glass tube adhere to it, which represents capillarity.
The effect of capillarity is more evident when the test tube is of a smaller diameter, although capillarity and adhesion to its walls always exist, and to a greater degree than any other substance.

B. All of the fish, bacteria, and mammals that live in a lake
C. All of the living and nonliving things that interact in and around a lake
D. All of the trout that live in a lake
Answer:
B. All of the fish, bacteria, and mammals that live in a lake
Explanation:
In terms of biology an individual make population, population makes a species and interaction between different species makes community. Interaction of living and non-living things make an ecosystem.
Community involves interaction between all the living organisms present in a given environment. Hence, interaction between fish, bacteria, and mammals that live in a lake is a community.
Hence, the correct answer is "B. All of the fish, bacteria, and mammals that live in a lake".

A population of Muscovy ducks contains 13 birds with black masks and 37 birds with red masks. Red masks are the dominant trait. What is the frequency of the black allele? What is the frequency of the red allele? What is the frequency of heterozygotes?
Answer: Black allele has frequency of 0.14.
Red allele has frequency of 0.86.
The frequency of heterozygotes is 0.241
Explanation: Hardy-Weinberg model states the frequency of alleles in a population will stay in equilibrium as long as there are external influences. It is also used to determine alleles frequencies using the following equations:
[tex]p+q=1[/tex]
[tex]p^{2}+2pq+q^{2}=1[/tex]
p represents frequency of dominant allele;
q represents frequency of recessive allele;
2pq is frequency of heterozygotes;
For the frequency of red allele, which is dominant, we can use:
[tex]p^{2}=\frac{37}{13+37}[/tex]
[tex]p^{2}=\frac{37}{50}[/tex]
[tex]p^{2}=0.74[/tex]
[tex]p=\sqrt{0.74}[/tex]
p = 0.86
For the black allele:
[tex]p+q=1[/tex]
[tex]q=1-p[/tex]
[tex]q=1-0.86[/tex]
q = 0.14
Frequency of heterozygotes is
2pq = 2(0.86)(0.14)
2pq = 0.241
Frequencies for a population of Muscovy ducks are 0.86 for red allele, 0.14 for black allele and 0.241 for heterozygote.
