Which of the following are characteristics of the tundra biome? (Choose all that apply.)
much rainfall throughout the year
low biodiversity
very cold temperatures
lack of trees

Answers

Answer 1
Answer is very cold temperatures, lack of trees and low biodiversity

The Tundra is defined mainly by permafrost, lack of trees, low biodiversity, and harsh conditions. It occupies the area between the polar ice caps and the boreal forests (or taiga).

The tundra biome is characterized by extremely cold temperatures and treeless, frozen landscapes. There are two types of tundra, the arctic tundra and the alpine tundra.

The World’s Ice Deserts: The Tundra Biome

The tundra is the coldest of all the biomes with an annual average temperature of less than 5°C, and precipitation (mostly in the form of snow) less than 100 mm per year. The weather conditions at tundra are so harsh that only a handful of plants and animals can even survive there. The word tundra comes from the Finnish word ‘tunturia’ which means treeless plain.

The tundra is one of the least understood and most fascinating biomes on the planet. This incredibly difficult climate and the environment have both a bizarre and diverse range of animals that have learned to survive with the limited amounts of green plant life, sunlight and moisture. Due to extremely cold temperatures, the layer just below the surface remains permanently frozen. This frozen layer of ground is called ‘permafrost.’
Answer 2

A lack of trees, a lack of biodiversity, and extreme circumstances are what most clearly identify the tundra.

What is Tundra Biome?

The polar ice caps and the boreal woodlands (also known as taiga), it is located. Extremely low temperatures and barren, icy terrain define the tundra biome. The arctic tundra and the alpine tundra are the two different forms of tundra.

The Tundra Biome: The Ice Deserts of the World. The tundra is the coldest biome, with an average annual temperature of less than 5°C and yearly precipitation of less than 100 mm, most of it snow.

Only a few number of plants and animals can even thrive on the tundra due to its extreme weather conditions. The Finnish term "tunturia" is where the word "tundra" originates.

Therefore, a lack of trees, a lack of biodiversity, and extreme circumstances are what most clearly identify the tundra.

Biomass produces gas or many sorts of waste products which are mostly used in burning and cooking. It is plant or animal material used as fuel to produce electricity or heat. Examples are wood, energy crops, and waste from forests, yards, or farms.

But the reason why it can be harmful is because biomass can produce gases like methane. Methane is a  greenhouse gas which can harm the environment and reduce the ozone layer that stops harmful UV light from reaching the earth atmosphere.

How does natural selection change the frequency of genes or traits over many generations? Biology students conducted an experiment mimicking genetic variation and coloration. Students used different colored beans to represent animals that might be prey: mice, for example. A student in each group was the predator: a hawk. Beans (mice) were randomly scattered on multicolored floor tiles, each color within four tiles. The hawk collected mice (beans) for 10 seconds. Mice not eaten reproduced. Three generations of data a shown in the table.
Genetic variation helps to drive natural selection and potentially, evolution. Red, white, and striped beans (mice) represent offspring that are the product of meiosis and sexual reproduction. Black and speckled beans (mice) are the result of mutations. Using the student data analyze the effects of these mutations on natural selection.

A) The color mutations provided a survival advantage to these two populations of mice.

B) The advantage of the mutations is dependent on the environment and external conditions.

C) While mutations provide genetic variation they did not play a role in natural selection.

D) The speckled mutation provided an advantage while the black mutation was a disadvantage for survival.

Answer:
D) The speckled mutation provided an advantage while the black mutation was a disadvantage for survival.

Answers

The speckled mutation provided an advantage while the black mutation was a disadvantage for survival.

Natural selection refers to the observation that organisms that are more suited and adapted to their environment live long enough to survive and reproduce thereby passing on their favorable characteristics to their offspring.

The mutation in which the mice became speckled was shown to be an advantage from the table. Hence, the speckled mutation provided an advantage while the black mutation was a disadvantage for survival.

When disaster strikes, an ecosystem can change very quickly. When an event causes a drastic decrease in a population, it can cause a type of genetic drift called a bottleneck effect.

Hope this helps ~

The bottleneck effect is an extreme example of genetic drift that happens when the size of a population is severely reduced. Events like natural disasters (earthquakes, floods, fires) can decimate a population, killing most individuals and leaving behind a small, random assortment of survivors.

Fraternal twins, while conceived at the same time, are not genetically identical.

Which statement best explains why these siblings are genetically different from each other?

A.One chromosome from each pair randomly passes to the sex cells during meiosis and leads to differences between the siblings.

B.One chromosome from each pair randomly passes to the sex cells during fertilization and leads to differences between the siblings.

C.Mutations occur during meiosis and lead to differences between the siblings.

D.Mutations occur during fertilization and lead to differences between the siblings.

Answers

Fraternal twins are not genetically identical because one chromosome from each pair randomly passes during meiosis and leads to differences between the siblings. Meiosis involves independent segregation of sex chromosomes.

Meiosis is a type of reductional cell division by which a parent cell produces four daughter (gametes) cells having half the genetic material.

Fraternal twins occur when two egg cells are released by the mother, which are fertilized by a different sperm.

During meiosis, sex chromosomes are separated and segregate in a random manner in daughter (sex) cells.
