How does respiration impact the amount of carbon in the atmosphere?

Answers

The process of respiration produces energy for organisms by combining glucose with oxygen from the air. During cellular respiration, glucose and oxygen are changed into energy and carbon dioxide. Therefore, carbon dioxide is released into the atmosphere during the process of cellular respiration.

During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses. The chromatin coils and becomes increasingly compact, resulting in the formation of visible chromosomes. Chromosomes are made of a single piece of DNA that is highly organized.

Which equation shows how matter is transformed and conserved in photosynthesis? In other words, which is the balanced chemical equation for
photosynthesis?
O 602 + 6H2O + Sunlight → CH208 + 6CO2
O 6CO2 + 6H2O + Sunlight → CH,20g + 602
O CH120o + 6CO2 → 602 + 6H20 + Sunlight
son
CH,208 + 602 → 6CO2 + 6H2O + ATP

Answers

Answer:

B

Explanation:

The reactants of photosynthesis are CO2 and H2O and the products are C6H12O2 and O2

the answer is not exact, but it is the closest to the actual equation

The equation shows how matter is transformed and conserved in photosynthesis is O 6CO2 + 6H2O + Sunlight → CH,20g + 602. Thus, option B is correct.

What is photosynthesis?

Photosynthesis can be described as a process which plants use to produce their own food. In this process, carbon dioxide and water get converted into sugar (glucose) and oxygen. Light energy from the sun is needed for this reaction to occur. The excess oxygen produced by this process is released into the atmosphere. The sugar made is used as fuel by the plant.

Cellular respiration is the process by which living organisms obtain energy by breaking down food molecules. Cellular respiration can occur in the presence of oxygen (aerobic) and this combines glucose molecule to form carbon dioxide (CO2) and water (H2O) and release energy for use.

The equation best models cellular respiration is: C6H12O6 + 602 = 6H20 + 6CO2 + Energy (ATP). The reactants of photosynthesis are CO2 and H2O and the products are C6H12O2 and O2.

Thus, option B is the correct option.

What is the linear momentum of an object with a mass of 10 kg and velocity of 100 m/s?

Answers

Here,

Mass of the object = 10 kg

Linear momentum of the object=100kg m/s

And , we have to find it’s velocity??

But we do know that linear momentum (p) is mass(m)× velocity (v)

P=m×v

V=p/m

Substituting the value here we get,

V= 10/100

Therefore, v= 0.1m/s.

describe evidence from biogeography that species evolve adaptations to their environment

Answers

Answer:

Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved. Fossils provide evidence of long-term evolutionary changes, documenting the past existence of species that are now extinct.

To give one classic example, the forelimbs of whales, humans, and birds look quite different on the outside. That's because they're adapted to function in different environments. However, if you look at the bone structure of the forelimbs, you'll find that the organization of the bones is remarkably similar across species. It's unlikely that such similar structures would have evolved independently in each species, and more likely that the basic layout of bones was already present in a common ancestor of whales, humans, and birds.

Vegetative propagation

Cutting is a form of vegetative propagation attribute of some organisms.

Cutting a tissue off a plant and the tissue developing its own root to become a new plant happens by mitosis.

Mitotic division of the cut tissues leads to the formation of roots and the eventual growth to a new plant.

Mitotic growth means that the new plant will be genetically and physically identical to the parent plant, provided they grow under the same conditions.

Answers

Linkage maps and physical maps are NOT the same. A linkage map measures the number of recombination events in a given chromosome fragment.

A linkage map is based on the frequency of recombination events between genes or molecular markers.

This frequency indicates the number of events in which a single chromosomal fragment recombines between two or more genes or molecular markers during meiosis.

Conversely, a physical DNA map indicates the physical locations of genes (molecular markers) and nucleotide (DNA) sequences of interest, which is useful to identify genes by positional cloning.

If you found a white sheep and wanted to determine its genotype, with what kind of animal would you cross it

Answers

The ideal would be to cross this sheep with several black sheep and observe the color of each offspring.

We can arrive at this answer because:

When crossing white sheep with black sheep it is possible to observe the genotypes of the offspring to determine the genotype of the white sheep.This will be even more efficient if we know the genotype of the black sheep.In this case, if the crossing of the white sheep with the black sheep generates an offspring with all individuals with black fur, we can determine that the white sheep has the h0m0zygous recessive genotype.If the offspring is composed entirely of individuals with white fur, we can state that the white sheep has the dominant h0m0zygous genotype.If the offspring have most of their members with white fur and a small amount with black fur, it means that the white sheep has a heterozygous genotype.

In this case, the observation of the offspring's fur is essential to determine the genotype of the white sheep.
