Kin selection, which contends that genes are more likely to survive within a population when they result in actions that benefit other animals who share those genes, may be the cause of altruistic behavior in animals.
What is the kin selection theory in animal behavior?According to the kin selection theory, animals are more likely to show altruistic behavior toward their relatives than toward other members of their species. Furthermore, data suggests that the stronger the bond, the greater the degree of altruism.
What does altruistic behavior theory entail?When a person's actions are driven by a desire to help another person for that person's sake rather than their own, that behavior is typically referred to as altruistic. The phrase is used to contrast with being "self-interested" or "selfish."

One would expect well-drained soils to have the highest organic matter contents where the climate is?
One would expect well-drained soils to have the highest organic matter contents where the climate is cool and humid.
What is organic matter?Reducing or eliminating tillage, which triggers a microbial action burst that hastens the decomposition of organic matter and raises erosion. Reduce erosion by taking the necessary action. SOM is mainly found in topsoil.The topsoil is the soil's topmost layer. The majority of the biological soil activity on Earth takes place there because it has the highest concentration of organic materials and bacteria.The topsoil is where most of the biological activity in the soil takes place and has the highest concentration of organic matter and nutrients. Without residue or living cover, soil is vulnerable to erosion.Histosols are soils that are rich in organic materials and unbroken plant matter.

describe the effects of altitude and latitude on the distribution of biomes
Answer:
As latitude and altitude increase, biomes and vegetation change. Trees of tropical rainforests usually grow closer to the equator, while mosses and lichen of the tundra grow closer to the poles.
Latitude determines the amount of sunlight received. The amount of sunlight and the amount of moisture received determines the ecosystem or biome. Biomes are partly determined by altitude. More precisely, biomes are mainly determined by temperature and precipitation, and the altitude can affect both temperature and precipitation. The temperature drops as the altitude increases. This would alter the structure and composition of our biome.

The scientific interpretation of the fossils found in the cradle of humankind,
The Cradle of Humankind region comprises 15 major fossil sites, some of which date back 5-million years.
The name Cradle of Humankind reflects the fact that the site has produced a substantially large number of hominin fossils, some the oldest ever found, dating as far back as 3.5 million years ago.
How was the Cradle of Humankind formed?The Cradle of Humankind Site comprises a strip of a dozen dolomitic limestone caves including the fossilized remains of ancient forms of animals, plants and most notably, hominids. The dolomite in which the caves formed, started out as coral reefs flourishing in a worm shallow sea about 2.3 billion years ago.

The Smokey the Bear campaign attempted to suppress and eliminate wildfires from forested areas altogether. Explain how fire suppression can negatively impact the health of a forest ecosystem?
A. Suppression allows weaker, more vulnerable trees that would have been weeded out by fire to survive.
B. Suppression leads to less diversity of tree species, so beetles spread more quickly between trees.
C. Suppression leads to equal/even-age stands of mature trees, which the beetles prefer.
1. Naturally occurring wildfires are most frequently caused by lightning
2. NATURAL forest fires can temporarily increase fertility of a region
3. burning process releases nutrients which then fertilize the soil.
3a. fire chemically converts nutrients bound in dead plant tissues and the soil surface to more available forms
3b. fire indirectly increases mineralization rates through its impacts on soil microorganisms (Schoch and Binkley 1986).
4. slash and burn process successfully clears land for agriculture and introduces fertilizing nutrients into the soil, leaving it in excellent condition to grow crops.

ASAP PLS There are lots of big words in genetics! One way to start thinking about the process of meiosis is to ask yourself some questions.
If two parents are contributing genetic material to their offspring, why don’t the genes and chromosomes double in each generation?
If each parent has two sets of genes and chromosomes, why do their offspring receive only one set from each parent?
Answer:
1) the genes and chromosomes do not double after each generations because parental sex cells are haploid and only contain one set of chromosomes. During fertilization the two cells fuse to form a diploid zygote with two copies of genes and chromosomes. For example a normal human has 46 chromosomes (2 copies of 23 chromosomes) during reproduction gametes which contain 23 chromosomes (haploid) fuse to form an offspring with the correct number of chromosomes ( 23 + 23 = 46).
2) offspring only receive one set of chromosomes from each parent so to maintain the chromosome number of humans. If this did not happen you would not be the same species.
Front legs of a cat and the arms of a human share a bone structure that suggests a common evolutionary lineage. Therefore these skeletal structures are
Answer:
homologous
Explanation:
Homologous organs are organs that share some similarities in different organisms but whose function differ in these organisms.
:)
Forelimbs of cat and arms of human share a similar bone structure, suggesting a common lineage. These type of common structure are said to be homologous structures.
Organs that function differently in different organisms but have some similarities are known as homologous organs. Although the organs are structurally similar, they serve different purposes. One of the arguments used by scientists to support evolution is the existence of homologous organs.
Even though their structures are based on the same five-digit plan, human arms and the front legs of cats serve different purposes.
Therefore, forelimbs of cat and forelimbs of humans are said to be homologous structures.
