what are some Major Characteristics Temperate Deciduous Forest
Answer:
The Temperate Deciduous Forest is a biome that is always changing. It has four seasons: winter, spring, summer, and fall. Constant rainfall and daylight saving hours also contribute.
Explanation:
Temperate deciduous forests get between 30 and 60 inches of precipitation a year, this helps keep the forest lush and green. When it comes to daylight savings in the fall, lack of sunlight can affect photosynthesis and the amount of sun the plant gets. Unlike the amazon forest, the temperate biome goes through all 4 seasons and has plant regeneration in the spring instead of constant vegitation.

How did tiktaalik provide evidence that amphibians evolved from fish?
Answer:
Tiktaalik fossils reveal how fish evolved into four-legged land animals. The report shows that the animal had a large, robust pelvic girdle, a prominent hip joint, and long hind fins. The powerful fins could have propelled the beast in the water, but also helped it walk on riverbeds, or scramble around on mudflats
The number of chromosomes is DOUBLED after mitosis. True or False, AND explain.
PLEASE HELP IT'S DUE TODAY!!!!
Answer:
False
Explanation:
The number of chromosomes is doubled during mitosis, but each daughter cell (new cell) has the same number as the mother (original cell)
Mitosis is a cell division cycle in which the parent cell divides to produce equivalent daughter cells. It can occur in the body for growth, replacing dead cells etc.
The statement is False.
The sentence can be explained as:
Mitosis is a function of division in cells in which the two exact daughter cells are produced from the parent cell division of the nucleus and cytoplasm.The parent cells undergo the doubling of the hereditary content by the process of central dogma during the synthesis stage. The parent and daughter cell is diploid during this sort of cycle and does not get halved or duplicated at the end of the cycle.Therefore, chromosomes do not get doubled at the end of the division.

What is one reason that a food web might be a better description of an ecosystem than a food chain?
O No animals are chained.
O Animals have only one option of what to eat.
O Organisms have a choice of what to eat,
At least one animal in the web has webbed feet.
One reason for which a food web might be a better description of an ecosystem than a food chain is that the organisms have a choice of what to eat. Thus, the correct option is C.
What is a Food web?A food web is the representation which consists of all the food chains in a single ecosystem. Each living thing in an ecosystem has the part of multiple food chains. Each food chain in the ecosystem is one possible path which the energy and nutrients may take as they move through the different ecosystems.
The food web shows more of the interactions which are present between organisms of the ecosystem and the trophic levels which are included from the different trophic levels such as producers to consumers to decomposers. In a food web, an organism have a choice of what to eat.
Therefore, the correct option is C.

Answer:

It is California & Arizona!
ArizonaArizona gets huge amount of sunlight. That's why Arizona is burning in the summer. During the summertime in Arizona, It can reach as hot as 120°F! It also ranked as No. 1 in the All-Time Record Maximum Temperature by State! In Lake Havasu City, it reached 128 °F! Arizona is also known for having heatwaves. About 76 people died during one of Arizona's heatwaves in 2014.
CaliforniaCalifornia is another state that gets a lot of sunlight. Since California gets high amounts of sunlight, most hurricanes form by California and Arizona. In September 6, 2020 California had recent a heatwave that broke out in several locations in Southern California. It reached 121 °F (49 °C), and a woman died while hiking.
That's all! Thanks for asking this question!The species of tree shown below grows in a wide range of temperatures in a desert area in Africa, where average temperatures have been rising over the past several
decades. The trees in the hottest parts of their range are dying, but trees at high elevations or in parts of the range that are cooler are growing and reproducing.
If this warming trend continues, which of the following statements best describes how the reproduction of trees will affect future generations of the species?
A. Trees in hotter regions will likely not survive and those at higher elevations will live to reproduce and pass their traits on to the next generation
B. The trees will adapt to the higher temperatures out of need and have offspring that are better suited for hotter temperatures.
C. Mutations in the somatic cells of individual trees that allow for resistance to heat will be passed along to future offspring.
D. Trees will adapt a method of dispersing seeds to higher elevations
Answer:
Explanation:b
Trees in hotter regions will likely not survive, and those at higher elevations will live to reproduce and pass their traits on to the next generation. This process is called as natural selection. Therefore, the correct option is A.
What is natural selection?Natural selection refers to the process through which the populations of the living organisms adapt and change to the changing environmental conditions.
In the scenario given here, if the warming trend continues, trees in hotter regions will likely not be able to survive due to the heat stress. Over time, the surviving individuals will pass on their traits to their offspring, resulting in a population better adapted to the warmer temperatures.
Option B is less likely because adaptation to higher temperatures can take a long time. Option C is incorrect because somatic mutations are not passed on to offspring. Option D is also unlikely, as it requires a complex change in behavior, and it's not clear if the species is capable of such adaptation. Therefore, the correct option is A.

A. They develop from the same embryonic
tissue.
Human
Bird
B. They are the most important sets of
bones.
C. They have no current use.
D. These animals do not share a common
ancestor.
Answer: its A
Explanation:
They have no current use, because they were passed down from a common ancestor, homologous structures are those that are comparable in related organisms, hence option C is correct.
What is homologous structures?The descendants of these structures may or may not carry out the same purpose. Tetrapods' four limbs are an illustration of homologous features. All four limbs are present in birds, bats, mice, and crocodiles.
Bony fish such as sharks do not. Tetrapods evolved four limbs, and their descendants have carried on this trait.
As a result, the presence of four limbs is a homology. The upper arm of both humans and cats consists of just one bone, which we refer to as the humerus, and two forearm bones, the radius on the more medial side and the ulna on the more lateral side.
Therefore, option C is correct.
