Answer:
[tex]\huge\boxed{Answer\hookrightarrow}[/tex]
It doesn't depend on whether the seal is a mammal or not. A seal has a thick layer of fat - 'blubber' that helps them to stay warm in the cold polar seas. This layer of fat or blubber is not found in humans as we live in warmer areas & hence don't have a need for it. So, humans will die in the cold polar seas without extra protection unlike seals.

Answers
Answer:
the classification of racial types is an arbitrary, culturally specific process.
Explanation:
Racism can be defined as an act, practice or policy by an individual, group of people or institutions which typically involves promoting the ideas and belief that a race is superior in comparison with another. Thus, it simply means the believe that a particular race has dominance over another (an inferior race).
An examination of the classifications of races from around the world indicates that the classification of racial types such as Africans, Americans, Indians, Asians, Black-Americans, Hispanics, etc., is typically based on individual perception, not objective and an impulsive (arbitrary), culturally inclined or specific process.
This ultimately implies that, the classification of racial types is considered not to be based on any form of objective distinction but may be defined by a person's culture.
A culture can be defined as the general way of life of a group of people living together in a particular location or society.
Basically, culture comprises of beliefs, values, behaviors, language, dressing, cuisine, music, symbols, arts, social habits, knowledge, customs, laws pertaining to a particular group of people living together in a society.

Label the figure below. Word bank: leading strand, lagging strand, DNA
polymerase, DNA helicase, replication fork
Answers
Answer:
DNA can replicate itself because its two strands are complementary. This means that one strand can be used as a template to make the other strand. It happens right before cell division via mitosis or meiosis so that each new daughter cell can have a complete genome.
Before replication can start, the double strands of DNA need to separate from each other. An enzyme called DNA helicase breaks the hydrogen bonds that connect the two strands, allowing them to come apart.
The point where this unzipping starts is called an origin point. Eukaryotic DNA can have more than one origin point, but prokaryotes can only have one.
The points where DNA is currently unwinding are called replication forks.

What is an oosphere in relation to biology

oosphere (ovum; egg cell) The nonmotile female gamete in plants and some algae. Explanation:
Much of our world is made up of plants, soil, and water. What do you think is
important about these three things? How do they interrelate?
Answers
Plants, soil, and water are interrelated to one another and help humans to sustain themselves on the earth's surface.
What do you mean by Soil?Soil may be defined as the loose surface material that covers most land. It consists of inorganic particles and organic matter.
Water makes the soil moisturized which increases its fertility. When soil becomes fertile, the number of plants grows which directly absorbs water through the xylem and mediates the process of photosynthesis. In this way, all plants, soil, and water are connected to one another.
Therefore, Plants, soil, and water are interrelated to one another and help humans to sustain themselves on the earth's surface.

A guard bees job is to protect the hive from intruders, a job that can lead the guard bee to sacrifice its own life. If the guard bee cannot reproduce, how do genes for altruism increase in the population
Answers
Answer:
Altruism genes are dominant, so they can be inherited more easily. Bee colonies are so large that the loss of a few individuals will not affect the gene pool.
Explanation:
The altruistic genes are easily and sophistically inherited from the parents to their offspring. These genes are dominant that increase the size of the population by sacrificing their own life for the benefit to pass their genes to the next generation.
What do you mean by Altruism?Altruism may be defined as a behavior in which one individual sacrifices their own fitness value to increase the fitness value of the other individual that is genetically as well as closely related.
Altruistic behavior is often associated with Kin selection. The genes for altruism are exposed to the population directly from the parents and then passes to the offspring.
Therefore, it is well described above.

Answers
Answer:
In psychodynamic therapy, therapists help people review emotions, thoughts, early-life experiences, and beliefs to gain insight into their lives and their present-day problems and to evaluate the patterns they have developed over time. Recognizing recurring patterns helps people see the ways in which they avoid distress or develop defense mechanisms as a method of coping so that they can take steps to change those patterns.
Explanation:
Answer: In psychodynamic therapy, therapists work with patients to examine their feelings, thoughts, early experiences, and beliefs in order to acquire understanding of their lives, their current issues, and the patterns that have grown over time. People can take action to change repeating behaviors by being aware of how they avoid distress or establish defense mechanisms by recognizing these tendencies.

Cells are the basis of the survival of human beings. We, the living organisms are made up of cells. If cells won’t divide no new organisms would originate.
What is cell division?
Cell division is the process by which a parent cell divides, when a mother cell divides into two or more daughter cells. Cell division usually occurs as part of a larger cell cycle. Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.
The existing cells will die and no new cells will be produced as there is no cell division.
