Answers
Lipids are used by the body as long term energy storage, for heat insulation, and are precursors to steroid hormones (ex: cholesterol is a precursor to estrogen and glucocorticoids).
It’s enzymes that speed up and start chemical reactions.

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.

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
Answers
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.

what are some Major Characteristics Temperate Deciduous Forest
Answers
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.

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.

Ribozymes
Ribosomal proteins
I only
I and II only
II only
I, II, and III
Answers
Answer:
1. and 2. only
Explanation:
rRNA is sometimes called a ribozyme or catalytic RNA.
Molecules of rRNA are synthesized in a specialized region of the cell nucleus called the nucleolus, which appears as a dense area within the nucleus and contains the genes that encode rRNA.
mRNA is Messenger RNA which are synthesized during DNA transcription as templates for the production of a specific proteins.
The molecules are produced during transcription are - Messenger RNA and Ribozymes that is - I and II only.
Transcription is the first step in decoding a cell's genetic information. During transcription, enzymes called RNA polymerases build RNA molecules that are complementary to a portion of one strand of the DNA double helix
the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA)carried out by an enzyme called RNA polymeraseproduces a number of accessory proteins called transcription factors.Ribozymes are catalytic RNA molecules. They have the intrinsic ability to break and form covalent bonds in RNA moleculesthus, The molecules are produced during transcription are - Messenger RNA and Ribozymes that is - I and II only.
