Answer:
presence of cells
Explanation:
All living things are composed of cells. A cell can be defined as a complex biological arrangement that has all the structures and materials required for life. Cells carry out specialized functions such as, for example, metabolic functions to convert nutrients from food into energy (ATP), and reproduce by mitosis and/or meiosis. Thus, the cell is known to be the basic unit of life.
Both prokaryotic cells and eukaryotic cells have genetic material in the form of DNA. True or false?
Answer: True
Explanation:
True. Both prokaryotic cells and eukaryotic cells have genetic material in the form of DNA.
What is DNA?DNA (Deoxyribonucleic Acid) is a molecule that carries genetic information in all living organisms. It is composed of long chains of nucleotides, which are the building blocks of DNA. Each nucleotide consists of a sugar molecule, a phosphate group, and a nitrogenous base. There are four types of nitrogenous bases in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T), and it is the specific sequence of these bases that determines the genetic information stored in DNA.
DNA controls the development, function, and replication of cells, and its information is passed from one generation to the next through the process of DNA replication. The study of DNA and its role in genetics is known as genomics, and advances in this field have led to a greater understanding of the genetic basis of diseases, evolution, and many other biological processes.

Block mountains are caused by faults in the crust, where rocks can move past each other in a rift and rise. The uplifted blocks become block mountains (also known as horsts) while The intervening dropped blocks are known as graben. Which mountain range is formed this way
Answer:
The Sierra Nevada mountain range of western North America, running along the eastern edge of the U.S. state of California.
Explanation:
Fault block mountains are also called fault mountains. They form as a result of expansion and contraction in the earth's crust.
Faults are cracks in the earth that are caused by tectonic movements. Rock layers on either side of a faults can now shift to form block mountains.
Some blocks are moved upward while others fall to lower heights.
The depression formed by the rock layers at the bottom are subject to erosion mountains form over time.
Sierra Nevada mountain range of western North America is an example of such mountain range. With mountain ranges referred to as the backbone of the Americas

The graph shows ice core data that illustrate historical trends in the amount
of carbon dioxide in Earth's atmosphere. Scientists attribute global warming
to recent increases in human activities that produce carbon dioxide. Which
kind of data would show that a new solution to the problem of global
warming is working?
A. Historic atmospheric CO2 levels would be the same as current
levels
B. Current atmospheric CO2 levels would be increasing at a steady
rate.
C. Historic atmospheric CO2 levels would no longer appear to
increase over time.
D. Current atmospheric CO2 levels would be increasing more slowly.
Answer: D. Current atmosphere CO2 levels would be increasing more slowly.
Explanation: A P E X
The graph shows historical trends in the amount of carbon dioxide in Earth's atmosphere. The data would show that a new solution is Historic atmospheric CO2 levels would no longer appear to increase over time.
What can cause the increase of CO2 in the atmosphere?In the last 200 years, the concentration of carbon dioxide in the atmosphere has increased by 27% — due to the burning of fossil fuels with the beginning of the industrial age and deforestation — with half of this increase occurring in the last 30 years.
A possible solution to reduce CO2 emissions would be to store it in underground brine, also generating geothermal energy and methane as fuels. So in the future, we will see a historic atmospheric CO2 levels would no longer appear to increase over time.

The gamete that contains genes contributed only by the mother is the?
A) the sperm
B) the egg
C) a zygote
D) dominant
Answer:
eggs
Explanation:
Answer:
The gamete that contains genes contributed by the mother is: an egg. Cells containing two alleles for each trait are descr. as: diploid. In meiosis, the way in which a chrom. pr. separates doesn't affect the way other prs. separate = independent assortment.

Answer:
Meisos is your answer.
Explanation:
Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells

A population of crabs live in an environment with white colored sand. Half of the crabs have white shells, and half have brown shells. Which color crab do you think is more likely to survive? What will the next generation of crabs look like? Explain your answer.
Answer:
The crabs with white shells. The next generation of crabs will be white shelled.
Explanation:
The crabs with white shells are more likely to survive because they blend in with the white sand more than the ones with brown shells making it easier to hide from predators and also makes it a desired trait.

Which mechanism produces this genetic diversity
Answer:
crossing-over
Explanation:
im not sure sorry if is wrong
Crossing over is the mechanism that produces the genetic diversity and alleles cross over and pair up, resulting in the genotype for an offspring.
What is Crossing over?When it will come to the genetics as well as genomics, the term "crossing over" has been described the exchange of the DNA that takes place between paired homologous chromosomes which means one from each parent at the time or during the formation of egg and sperm cells (meiosis).
This mechanism leads to novel allele combinations in the gametes (egg or sperm) generated, ensuring genetic variety in any baby born. Crossing over is a cellular process that happens during meiosis when chromosomes of the same type are lined up. When two chromosomes one from the mother and one from the father would line up, parts of the chromosome can be switched.
Therefore, Crossing over is the mechanism that produces the genetic diversity and alleles cross over and pair up, resulting in the genotype for an offspring.
