Which term best describes the expression 137 rabbits per km2?a. exponential
b. density
c. biome
d. size

Answers

Answer 1
Answer: b. density

Km^2 (kilometers squared) is an area of land, so 137 rabbits per km^2 describes the density of rabbits in a given area

Km^2 does have an exponent, but "exponential" has nothing to do with 137 rabbits. A biome is a type of landscape, merely knowing the density of rabbits would not tell the biome. This expression counts the number of rabbits within an area, not just the size of rabbits or size of land area.
Answer 2
Answer:

Answer: The answer is b. density

Explanation: I took the test off of k12 and it was correct.

How does heredity affect a species

Answers

Heredity, the sum of all biological processes by which particular characteristics are transmitted from parents to their offspring. The concept of heredity encompasses two seemingly paradoxical observations about organisms: the constancy of a species from generation to generation and the variation among individuals within a species. Constancy and variation are actually two sides of the same coin, as becomes clear in the study of genetics. Both aspects of heredity can be explained by genes, the functional units of heritable material that are found within all living cells. Every member of a species has a set of genes specific to that species. It is this set of genes that provides the constancy of the species. Among individuals within a species, however, variations can occur in the form each genetics, providing the genetic basis for the fact that no two individuals (except identical twins) have exactly the same traits.

After studying about recycling, members of Miguel’sbiology class investigated the effect of various

recycled products on plant growth. Miguel’s lab

group compared the effect of different aged grass

compost on bean plants. Because decomposition is

necessary for release of nutrients, the group

hypothesized that older grass compost would produce

taller bean plants. Four flats containing the same

species of bean plants (25 plants/flat) were grown for

5 days. The plants were then fertilized with compost

as follows: (a) Flat A: 450 grams of two-month-old

compost; (b) Flat B: 450 grams of four-month-old

compost; (c) Flat C: 450 grams of six-month-old

compost; (d) Flat D: 0 grams of compost. The flats

of beans were planted in the same type of soil. The

plants received the same amount of sunlight and

water each day. At the end of 30 days, the group

recorded the height of the plants in centimeters. What is the flaw in this experiment?

Some species of bees help flowers reproduce by transferring pollen from one plant to another. Flowers provide a source of food, such as nectar or pollen, for the bees.Which term BEST describes the symbiotic relationship between bees and flowers?
A
commensalism

B
mutualism

C
parasitism

D
predation

Answers

Answer:

Option B. mutualism

Explanation: Mutualism is a symbiotic association in which both the organisms gets benefits from one another. Bees helps in the pollination by transferring pollen grains from one plant to another and in return the flowers provide food in the form of nectar to the bees and in this way both the organism gets benefited. So the relationship which is present between flower and bees

is Mutualism.

HELP 25 POINTS WILL MARK BRAINLIEST PLEASEWhat characteristics of Venus’s atmosphere make the planet so harsh? Name 4 things. Please don't copy-paste from google because that isn't 4 things.

Answers

Answer:

Explanation:

1) Too much CO2 (at about 95-96%) thus not habitable by any living being since we all need oxygen.

2) Too much CO2 also gives chance for more acid rain of sulfuric acid which has tremendous effect on the environment and human health thus this is second thing that makes it harshest.

3) CO2 is greenhouse gas thus traps heat sent by Sun so it is completely inhabitable due to its distance to sun and the rays of sun being trapped which increases the atmospheric temperature.

4) There's alot volcanic eruptions on the surface making life impossible to survive/live so that's harsh. Some predict there to be 1,600 major volcanoes on Venus.
