Answer:
The Answer is A
Explanation:
B would be incorrect, since it is only found on 3 biomes. C is also incorrect, as there is only 2 distinct seasons. D is false because taiga biomes are very cold, and theres always snowfall there. Leaving the last answer as A.
Taiga biome is a boreal forest with coniferous trees that has major life zones and thick forest zones. It is the largest biome on the globe. Thus, option a is correct.
What is the Taiga biome?Taiga biome is the snow or the boreal forest that has a cone, pine-bearing trees, and evergreen trees in its region. They are characterized by the long winters and high to moderate precipitation rates.
It covers 11% of the land and hence is the largest biome on the land, located in the northern hemisphere, covering North America, Alaska, and Canada. They are characterized by the presence of coniferous trees with freezing winters, and hot summers along with humid rainy seasons.
Therefore, the taiga biome is the largest biome in the world.

Phenotype determines genotype. If false, make it a correct statement.
A. True
B. False
Answer:
The correct answer is B. False
Explanation:
The genotype of an organism determines its phenotype. Phenotype is constituted by observable characteristics of an organism. These characteristics are codified by genes, and the combination of the differents variants of a gene which codify a phenotipic characteristic constitutes the genotype. For example: eyes color is a characteristic. Its is codified by variants of a gene. The combination of two variants of a gene gives a genotype, which codifies for the phenotype 'blue eyes'.

35. To study whether the average house cat prefers a chicken-based food or a vegetable-based food,
Arianna provided her cat with equal amounts of each kind of food at every meal time for a week. What
is the source of error in her experiment?
Answer:
She should involve one more than one cat in the experiment.
Explanation:
Errors are the mistakes happened in an experiment that causes results that are inaccurate in nature.
There is one error in the given experiment that Arianna should perform the experiment in more than one cat to find more accurate results. This is so because only one cat will not be able to give all the effects or side-effects of the food and the involvement of more cats will help to find more accurate observation.
Hence, the correct answer is "She should involve one more than one cat in the experiment."

Imagine a pool ball that bounces off of a bumper and
slowly comes to a halt. Explain what happened at each point in terms of applied
forces and energy transfer
Answer:
The kinetic energy is transferred from the ball to the bumper. The bumper gives the same energy back and the ball eventually stops due to friction of the ground.
Explanation:
Hope this helps y'all <3
When a ball bounces off of a bumper and slowly comes to a halt. The transfer of energy takes place from the ball to the bumper and the ball keeps on bouncing until all the energy is transferred.
What is Energy transfer?Energy transfer takes place when two objects comes in contact due to collision or bouncing. The energy from the moving body is transferred to the body in rest.
In the given situation, elastic potential energy is causing the ball to bounce, or rebound, because it is transformed into kinetic energy, which is then used to bring the ball back up.
When a ball is dropped, the gravity pulls ball towards the ground, which slows the ball down so with each bounce the height becomes shorter and shorter, until eventually the ball stops bouncing. On the other hand, the force of the ball hitting the ground puts an equal force back onto the ball which bounces the ball back up.

Each enzyme has an optimum pH range. Changing the pH outside of this range will slow enzyme activity. Extreme pH values can cause enzymes to denature. Enzyme concentration: Increasing enzyme concentration will speed up the reaction, as long as there is substrate available to bind to.
What is the role of the gametophyte in fernsg?
Answer:
The gametophyte produces the haploid gametes
Explanation:
Ferns are a group of lower plants that also undergo the ALTERNATION OF GENERATIONS in their reproductive life cycle. The plant consists of the SPOROPHYTE and GAMETOPHYTE. The sporophyte is a diploid plant body that produces the haploid spores via meiosis. These spores are released on the sporangium and grow into a haploid GAMETOPHYTE.
The gametophyte produces the haploid GAMETES i.e. male gametophyte (antheridium) produces sperm while female gametophyte (archegonium) produces eggs, which undergo fertilization to produce a diploid zygote that develops into the sporophyte. The cycle begins again.
Myrmecia pilosula was originally described as a single species, however, after closer examination, it was determined to consists of several distinct, closely related, physically similar species. Females have chromosome numbers of 2, 18, 20, 32, 48, 60, 62, and 64. Assume that a cross is made between a female of species (A) with 48 chromosomes and a male species (B) with 10 chromosomes (males are haploid and transmit all their chromosomes to each sperm cell). How many chromosomes would be expected in the somatic cells of the hybrid female offspring?
Answer:
The correct answer is "34".
Explanation:
The ant Myrmecia pilosula is a special case of sexual reproduction, where the females produce gamete cells with half the chromosomes of the somatic cells and the males are haploids that transmit the whole number of chromosomes in their gametes. Therefore, the somatic cells of the hybrid female offspring that results from the cross of a female ant with 48 chromosomes and a male with 10 chromosomes would have 34 chromosomes. This result from half the number of chromosomes of the female (24) plus the total number of chromosomes of the male (10).

Baleen whales use _____ to prey on herring fish.
1.) an oily glandular secretion
2.) low pitched sounds
3.) bubbles
4.) phytoplankton swarms
5.) temporary increases in water temp
Answer:
They use bubbles.
The most well-known method for Baleen whales to catch herring fish is the bubble net feeding method. Therefore, option (3) is correct answer.
What is the bubble net feeding method?Baleen whales, sometimes known as whalebone whales, are a suborder of carnivorous marine mammals that belong to the infraorder Cetacea. To filter planktonic organisms from the water, baleen whales use keratinaceous baleen plates in their mouths, which are similar to whalebones.
When feeding by bubble-net, whales descend to great depths below schools of fish and then use the bubbles released from their blowholes to daze and catch fish that are swimming closer to the surface. In most cases, one whale will take the initiative, followed by the other members of the group.

1. The type of organism that possess cell exposed to the environment from all sides is.
O unicellular organism
O multicellular organism
O plants
O animals
Answer:
unicellular organism
Explanation:
The type of organism that possesses a cell exposed to the environment from all sides is unicellular organism, option A is correct.
Unicellular organisms, as the name suggests, are composed of a single cell that functions as both the basic unit of life and the interface with the environment. These organisms, including bacteria, protozoa, and some algae, carry out essential processes such as respiration, nutrition, and reproduction within this singular cell.
Due to their simplicity and direct exposure, they can efficiently exchange substances with the surrounding environment from all sides. In contrast, multicellular organism, like plants and animals, possess specialized cell types organized into tissues and organs, limiting direct environmental contact to specific cell surfaces. This fundamental difference in cellular organization is a key characteristic that distinguishes unicellular organisms from their multicellular counterparts, option A is correct.
