Which of these occurs in sexual reproduction but not in asexual reproduction?
a
The genetic information is identical to the parents.
b
The offspring are made of cells.
c
The genetic information comes from the parents but is not identical.
d
The offspring inherit traits from the parents.

Answers

Answer:

c

Explanation:

Only in asexual reproduction the genetic information is identical. Sexual produces genetics that are combination of both parents, producing non-identical offspring.

using the graph, the temperature seasonal force from the other Forest biomes. choose all the apply

A) the temperature seasonal Forest averages 100 to 200 cm rainfall/year

B) the temperature seasonal Forest is cooler and wetter than the tropical rainforest

C) the temperature seasonal Forest has warmer average temperatures than the Boreal forest

D) the temperature seasonal rainforest has similar temperatures but less rain than the temperate rainfores

E) the temperature seasonal rainforest has similar rainfall to the Boreal and tropical seasonal rainforest, but is much warmer than either one​

Answers

Answer:

The correct answer is - A and C,

Explanation:

According to the graph, the following conditions are matched correctly with the temperature seasonal forest with other biomes:

The temperature seasonal forest has the precipitation range from 50 cm to 250 cm rainfall per year approximately. The average rainfall from this would be 150 cm/year or between 100 to 200 cm per year.

B. the temperature seasonal forest has a temperature between 15 degrees Celsius to 20 degrees celsius which is warmer than the boreal forest that has a temperature between 0 to 15 degrees Celsius approximately.

tRNA uses (anticodons/codons) to match to the mRNA.

Answers

Answer:

anticodons

Explanation:

codons are for mRNA

tRNA uses anticodons to match to the mRNA.

Which one does tRNA uses?

tRNA (transfer RNA) molecules are responsible for carrying specific amino acids to the ribosomes during protein synthesis.

They have an anticodon region that consists of three nucleotides that are complementary to the codons on the mRNA (messenger RNA). The codons on the mRNA determine the sequence of amino acids in the growing polypeptide chain.

The anticodon on the tRNA base pairs with the complementary codon on the mRNA, ensuring that the correct amino acid is incorporated into the growing protein chain. The matching between the anticodon and codon is essential for the accurate translation of genetic information into protein synthesis.

Select the correct answer. Which statement about natural selection is true? A. Natural selection and evolution are two terms for the same phenomenon. B. Natural selection is an outdated theory to explain how evolution took place. C. Natural selection is the process by which organisms with more beneficial traits are more likely to survive and reproduce. D. Natural selection is the process by which organisms develop variation in traits, which gives them a better chance of survival.

Answers

Answer:

C. Natural selection is the process by which organisms with more beneficial traits are more likely to survive and reproduce.

Explanation:

Natural selection is an evolutional process by which species of living organisms with stronger or more beneficial traits have higher chances of survival and reproduction. In other words, it is the process by which organisms adapt and survive.

Organisms in a population are all different in their own ways. And those with characteristics or traits better suited for the environment are more likely to survive than those without. The selection prefers more beneficial traits and not wholly on the superiority of the organism. So, the survival and reproduction chance of an organism depends on the presence of traits beneficial to the environment, which is how nature selects. And in this process, those selected will dominate the population while those rejected will be reduced or even die.

Thus, the correct answer is option C.

and function of organisms.
Chromosome

Answers

Answer:

- DNA is wrapped around nucleosomes and condensed into chromosomes.

- Proteins affect the traits and function of organisms.

Explanation:

Nucleosomes are the basic unit of compaction of DNA. Each nucleosome is composed of ~148 bp double-stranded DNA and an octamer of histone proteins, which include two molecules of each core histone: H2A, H2B, H3 and H4. Subsequently, nucleosomes are packaged into chromatin fibers so they can be densely compacted into chromosomes. On the other hand, proteins are molecules that play important (structural and enzymatic) functions in a cell. These proteins may affect the structure/function of a cell, thereby affecting a certain characteristic/trait to develop.

Will give Brainliest within five minutes of answer - Why do we want to explore Mars more than the other planets/moons even though it is not currently habitable (with its temperatures, atmosphere, etc.)? How can it be habitable?

Answers

Answer:

After the Earth, Mars is the most habitable planet in our solar system due to several reasons:

Its soil contains water to extract

It isn’t too cold or too hot

There is enough sunlight to use solar panels

Gravity on Mars is 38% that of our Earth's, which is believed by many to be sufficient for the human body to adapt to

It has an atmosphere (albeit a thin one) that offers protection from cosmic and the Sun's radiation

The day/night rhythm is very similar to ours here on Earth: a Mars day is 24 hours, 39 minutes and 35 seconds

The only other two celestial bodies in orbits near the Earth are our Moon and Venus. There are far fewer vital resources on the Moon, and a Moon day takes a month. It also does not have an atmosphere to form a barrier against radiation. Venus is a veritable purgatory. The average temperature is over 400 degrees, the barometric pressure is that of 900 meters underwater on Earth, and the cherry on top comes in the form of occasional bouts of acid rain. It also has nights that last for 120 days. Humans cannot live on Mars without the help of technology, but compared to Venus it's paradise!

Additional info:

Mars is an obvious target for exploration because it is close by in our Solar System, but there are many more reasons to explore the Red Planet. The scientific reasons for going to Mars can be summarised by the search for life, understanding the surface and the planet’s evolution, and preparing for future human exploration.

Searching for life on Mars

Understanding whether life existed elsewhere in the Universe beyond Earth is a fundamental question of humankind. Mars is an excellent place to investigate this question because it is the most similar planet to Earth in the Solar System. Evidence suggests that Mars was once full of water, warmer and had a thicker atmosphere, offering a potentially habitable environment.
