Answer:

This is an example of molecular evidence for evolution.

Explanation:

This is an example of molecular evidence for evolution. Molecular evidence for evolution refers to the study of the genetic makeup of different species to understand their evolutionary relationships. In this case, the scientist is comparing the DNA sequences of two different groups of primates and observing that the average difference is relatively small. This suggests that these species are closely related and likely evolved from a common ancestor, providing evidence for the theory of evolution.

two of the steps in the oxidative decarboxylation of pyruvate (steps 4 and 5 in the figure) do not involve any of the three carbons of pyruvate, yet are essential to the operation of the pyruvate dehydrogenase (pdh) complex. Why are steps 4 and 5 essential to the operation of the PDH complex?• They transfer a thiol group from coenzyme A to acetyl lipoyllysine.• They reduce the disulfide bond in oxidized lipoyllysine.• They reoxidize the reduced lipoamide cofactor.• They catalyze the synthesis of hydroxyethyl thiamine pyrophosphate (TPP).

Answers

The two steps catalyzed by dihydrolipoyl dehydrogenase (E3) are required to regenerate the oxidized form of lipoate, bound to dihydrolipoyl transacetylase, from the dihydrolipoyl (reduced) form produced in the oxidation of pyruvate. First, FAD is reduced to FADH2 to reoxidize the dihydrolipoate, then NAD+ is reduced to NADH to reoxidize the FADH2 to complete the reaction.

What three steps are included in the breakdown of pyruvate ?

Pyruvate, which is created during glycolysis, enters the mitochondria to start aerobic respiration. Pyruvate is converted to acetyl CoA to start aerobic respiration. Decarboxylation, NAD+ reduction, and coenzyme A attachment are the three steps that make up this conversion.

To create acetyl CoA, pyruvate is subjected to oxidative decarboxylation. A byproduct of glycolysis is pyruvic acid. In the presence of the pyruvate dehydrogenase complex, pyruvate is oxidized.

O A glacier retreats, leaving behind a large area of rock.
O Warming temperatures in the spring thaw soil upon which seeds and fungal spores can grow.
O The ocean water falls back as the tide goes out, exposing a large stretch of sandy ocean front.

Answers

The primary succession might successfully occur in the glacier retreats, leaving behind a large area of rock. Thus, the correct option is B.

What is Primary succession?

Primary succession is a type of ecological succession. Ecological succession is the evolution of a biological community's ecological structure in which the plants and animals first colonize on a barren, lifeless habitat such as a rock.

Primary succession happens in places where a new patch of land is created or exposed for the first time and no living organism has ever found in that area. This can happen when the lava cools and creates new rocks, or when a glacier retreats and exposes rocks without any soil on the land. During primary succession, organisms must start from the beginning as conditions are not favorable.

Therefore, the correct option is B.

Sharon wants to conduct an experiment to determine if increasing the concentration of atmospheric carbon dioxide around a plant will affect the plant's rate of photosynthesis. The correct option is C  4-3-2-1 .

   

Plants and other living things employ a process called photosynthesis to transform light energy into chemical energy that can then be released through cellular respiration to power the organism's activities. The word "photosynthesis" comes from the Greek words "light" and "putting together," and refers to the process of creating molecules of carbohydrates from carbon dioxide and water. These molecules, such as sugars and starches, are then stored with some of this chemical energy. [1] [2] [3] Photoautotrophs are creatures that perform photosynthesis, including most plants, algae, and cyanobacteria. The majority of the energy required for life on Earth is produced and maintained by photosynthesis, which is also substantially responsible for producing and maintaining the oxygen content of the atmosphere.

Even though various species perform photosynthesis in different ways, the process always starts when energy from light is absorbed by proteins called reaction centers that contain the colored pigments/chromophores green chlorophyll (and other colors). Unlike bacteria, which have these proteins incorporated in the plasma membrane, plants store these proteins in organelles called chloroplasts, which are most prevalent in leaf cells.

a food web cascade occurs when one species has an indirect effect on species at a different level of the energy pyramid (true or false).

Answers

FALSE. Whenever one species has had an indirect impact on species at a nother scale of the energy pyramid, this is known as a food web cascade.

The ecological phenomenon known as trophic cascade, which involves reciprocal shifts in the relative populaces of predator and prey along a food chain, is triggered by the addition or deletion of top predators. This phenomena typically has significant consequences on the structure of ecosystems and the cycling of nutrients. But extinction seems likely to happen if environmental conditions shift too quickly for a species to adapt so if individuals from such a species lack the traits required to survive in a new environment.

Answers

Answer:

1. Ingrid's blood type is BO.

2. No, Lars could not be the father.

3. Yes, Sven could be the father.

Explanation:

Ingrids blood type is BO because she had to have an O recessive allele in order to have an O child. This means that her man has to have an O allele as well.

Lars has AB blood type so he has two dominant alleles that will always mask an O recessive. Lars children will never have an O blood type regardless of the female.

Sven has blood type A. Technically this could be he is AA or AO. However, the only way for Ingrid to have an O child is if the father also has an O allele so this means Sven has blood type AO.
