Which of the following subatomic particles do not have a charge?

What molecules can produce more energy per gram than sugar is in a used for storing energy in animals

svetoff [14.1K]

Answer:

Lipids store about 9 kilocalories of energy per gram, almost twice that of carbohydrates, so they are the preferred fuel in the animal body. Glucose has one great advantage, however, it is soluble in water and blood and thus easy to distribute around the body.

What are the different ways in which a genetic condition can be inherited?

Some genetic conditions are caused by mutations in a single gene. These conditions are usually inherited in one of several patterns, depending on the gene involved:

Patterns of inheritance

Inheritance pattern Description Examples

Autosomal dominant One mutated copy of the gene in each cell is sufficient for a person to be affected by an autosomal dominant disorder. In some cases, an affected person inherits the condition from an affected parent. In others, the condition may result from a new mutation in the gene and occur in people with no history of the disorder in their family. Huntington disease, Marfan syndrome

Autosomal recessive In autosomal recessive inheritance, both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition. Autosomal recessive disorders are typically not seen in every generation of an affected family. cystic fibrosis, sickle cell disease

X-linked dominant X-linked dominant disorders are caused by mutations in genes on the X chromosome, one of the two sex chromosomes in each cell. In females (who have two X chromosomes), a mutation in one of the two copies of the gene in each cell is sufficient to cause the disorder. In males (who have only one X chromosome), a mutation in the only copy of the gene in each cell causes the disorder. In most cases, males experience more severe symptoms of the disorder than females.

A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons (no male-to-male transmission)

(NEED HELP ASAP) BRAINLIEST NO FAKE ANSWERS

konstantin123 [22]

Answer:

scientist is attempting to build a cladogram that shows the evolutionary closeness of three organisms in relation to humans. After doing DNA analysis, they determine that the organisms share the following percentages of DNA:

Organism A and humans share 85% of their DNA.

Organism B and humans share 80% of their DNA.

Organism C and humans share 90% of their DNA.

Based on this information, which order should they go on the cladogram (from least related to most related)?

(1 point)

A, B, C, humans

C, B, A, humans

C, A, B, humans

B, A, C, humans

2.A cladogram shows the evolutionary relationship between humans, chimpanzees, and gorillas. The cladogram currently shows humans and chimpanzees with a more recent common ancestor compared to gorillas. Which piece of evidence, if true, would most likely weaken this hypothesis?(1 point)

Fossils of humans appear in deeper sedimentary rock layers compared to fossils of chimpanzees.

Amino acid analysis of the cytochrome c protein shows significant differences in the sequence of amino acids between humans and gorillas.

DNA sequence analysis of the hemoglobin alpha gene shows that humans and chimpanzees have a more similar sequence to each other than they do to the gorilla’s DNA sequence.

The cells of the eye in embryos of gorillas and humans follow a similar pattern of development while chimpanzee embryos are different.

3.The forelimbs of bats and humans have a very similar bone structure even though they appear very different on the outside. These structures are known as __________ because they result from species evolving __________.

Which of the following answer choices correctly completes the above statement?

(1 point)

homologies; similar adaptations in similar environments

analogies; from the same common ancestor

analogies; similar adaptations in similar environments

homologies; from the same common ancestor

4.All vertebrate embryos have a tail and gill slits at some point during embryonic development. What does this suggest about vertebrates?(1 point)

The embryos of these species require these structures to survive.

These species evolved in similar environments.

These species have the exact same DNA sequence.

These species share a common ancestor.

5.Fossil A is found closer to the surface compared to Fossil B. Which of the following conclusions can be made based on this statement?(1 point)

Fossil A is from an older species than Fossil B.

The species of Fossil A existed at the same time as the species of Fossil B.

The species of Fossil A evolved from the species of Fossil B.

Fossil B is most likely older than Fossil A.

6.Vertebrate embryos all follow a very similar developmental process. Which statement could explain this similarity?(1 point)

All vertebrates require the same nutrients during embryological development.

All vertebrates develop a backbone that protects the spinal cord.

All vertebrates inherit the same sequence of DNA from their parents.

All vertebrates live in similar environments which require the same adaptations.

7.Some mutations, or changes in the sequence of DNA, do not have any effect on the characteristics of the organism. Why is this?(1 point)

The immune system repairs the mutated sequence during development.

The protein built from this mutated sequence is deactivated by the cell.

The mutated sequence still codes for the same amino acid.

The cell recognizes mutations and ignores them when expressing the gene.

8.What is typically studied when analyzing not-yet-born (or unhatched) animals?(1 point)

embryological development

evolutionary theory

causal records

DNA sequencing

9.What can scientists analyze to get a better understanding of how plants and animals evolved from a common ancestor?(1 point)

petrified bones and imprints of plants

DNA molecules

vertebrate embryos

life cycles and behaviors

10.How can embryos help scientists understand evolution?(1 point)

Embryos contain the code for all life on Earth.

Embryos go through various stages that suggest the animal’s evolutionary process.

Embryos provide evidence for which life forms existed at the same time.

Embryos are frequently fossilized and illustrate change over time.

11.Astronomers have made great strides in sending probes out to other planets and moons in our solar system. If they were to find a living creature some place other than Earth, how could DNA analysis help them better understand the organism? Explain in 1–2 sentences.(2 points)

12.In 1973, biologist Theodosius Dobzhansky wrote an essay titled “Nothing in Biology Makes Sense Except in the Light of Evolution.” Why is evolution so important for understanding biology? Explain your answer in 1–2 sentences.(2 points)

13.You are a scientist tasked with writing a journal article on the evolution of alligators. In 3–5 sentences, describe the different forms of evidence you might use to analyze the evolution of alligators.(4 points

The atlantic cod (gadus callarias) is a fish which lays about 5 000 000 eggs in its lifetime. On average, only two of these eggs

lozanna [386]

The atlantic cod (gadus callarias) is a fish which lays about 5 000 000 eggs in its lifetime. On average, only two of these eggs survive to become adult cod. This promote evolution because the environment selects the most evolved animals to survive that environment.

<h3>What is the evolutionary process?</h3>

Evolutionary processes aim, therefore, to generate greater adaptation of species in an environment. When new species of organisms are formed from gradual changes in preexisting species.

So although there are several eggs initially only those that survived the environment are able and evolved to reproduce, so the evolution of species is carried out.

Using the brake pedal analogy, explain the impact of ONE mutated tumor suppressor gene allele versus TWO mutated tumor suppresso

GrogVix [38]

The tumor suppressors allele is analogous to the brake pedal in a vehicle while cyclins are like the gas pedal. The tumor supressors regulate, negatively, the replication of cells. If the tumor supressor is mutated, this is analogous to the brake pedals of the vehicle being broken, This means that if two are broken, then the vehicle will be unable to stop and will continue moving. This same way, if tumor suppressors are mutated, the replication of cells will continue unregulated and casue a tumor.
