Crossing over occurs at the ends of chromosomes, rather than near the centromeres. As a result of crossing over, sister chromatids are no longer identical to each other. For crossing over to occur, homologous chromosomes must align precisely early in prophase I so that nonsister chromatids can exchange corresponding segments of DNA. Crossing over prevents homologous chromosomes from separating during meiosis I.

3. How does saving the lynx maintain biodiversity?​

Answers

Answer:

Lynx, like other forest hunters, play an important ecological role. As a mid-size carnivore, lynx target smaller prey species that reproduce relatively quickly. When the lynx become fewer, they catch fewer hares. Thus, the number of hares increases, and the cycle repeats itself.

Explanation:

Practically exhaustively weakened population of Iberian Lynx affects the health of the whole ecosystem in which they inhabit.

What is biodiversity?

The devastation of the inhabitants of the Iberian Lynx decreases the Biodiversity of the ecosystem in which the Iberian Lynx rooms which hinders the whole ecosystem’s capacity to endure.

Lynx, like different forest hunters, play a significant ecological role. As a mid-size carnivore, lynx target more diminutive prey species that reproduce relatively fast. When the lynx evolve more irregularly, they catch fewer hares. Therefore, the number of hares increases, and the cycle repeats itself.

What type mutation are most harmful to an organism

Answers

Answer:

type 1

Explanation:

Because an insertion or deletion results in a frame-shift that changes the reading of subsequent codons and, therefore, alters the entire amino acid sequence that follows the mutation, insertions and deletions are usually more harmful than a substitution in which only a single amino acid is altered.

Which of the following are pieces of evidence showing common ancestry among species?

Answers

Answer:

1. The pieces of evidence that support the theory of evolution include the following:

a. Fossil records/evidence

b. DNA of the organisms

c. Comparative anatomy

2. Whales have features that are similar to land mammals, such as the presence of hip bones and the need to breathe air. In this case, the whale fossils indicate that the modern whales that we see today have evolved from the land-dwelling mammals that existed 50 to 70 million years ago.

3. According to Darwin’s theory of evolution through the process of natural selection, the presence of a trait that is observed throughout the timeline of divergence of species is used as evidence that supports the idea that certain organisms share common ancestors.

In this case, comparative anatomy can provide the scientists the evidence that the organisms which share anatomical or structural similarities have common ancestry; hence, supporting the theory of evolution.

Answers

The correct option for this question is as follows:

a) they are made of many cells

b) they are made of one or more cells

c) they come from the same kind of cell

d) they come from noncellular structures

Answer:

The correct answer is - option b. they are made of one or more cells

Explanation:

The cell theory has three major parts that are; the cell is the basic and physiological unit of the organism, all living organisms are made up of one or more cells, new cells come from the pre-existing cells.

On the basis of the cell theory, we can say that all organisms including the cheetah that is a multicellular organism or paramecium a single-celled organism, are made up of one or more cells.

Answers

Complete question:

Fill in the blanks.

The earth is ______ (warming, cooling, static, dynamic). This trend most closely follows trends in the Earth's ______ (albedo, distance from the sun, energy input from the sun, atmosphere). Within the Earth's ______ (albedo, mantle, atmosphere, crust) the component that is likely most responsible ______ (carbon dioxide, magma, water, humans).

Answer:

The earth is warming. This trend most closely follows trends in the Earth's atmosphere. Within the Earth's atmosphere is the component that is likely most responsible for carbon dioxide.

Explanation:

Carbon dioxide (CO₂) is a gas that, among other gases, composes the atmosphere, mainly the troposphere, which is closest to the Earth. The balance of this gas in nature is very complex and involves interactions between the atmosphere, the plants, and the oceans.

The current increase in CO₂ is a responsible component of the greenhouse effect involved in global warming and climate change. The rise in CO₂ is possibly the best documented.

The atmospheric increase of CO₂ follows a natural fluctuation trend that has been happening throughout the whole Earth´s history. It has been proven that the current rise in CO₂ concentration overlaps the expected variation and that the reached levels at the moment exceed the highest past registered levels. This substantial increase must be related to human activities.

need help asap im begging you guys

Answers

Plants and other organisms that use sunlight absorb it and then use that energy to make their own food. That energy passes to other organisms that eat the plants. For example, grass uses sunlight to make food. A deer gets energy by eating the grass. After that, a wolf gets energy by eating the deer.

So according to the scientific explanation of how food from plants provides energy for body processes.

Through the system of mobile respiration, the electricity in meals is modified into electricity that may be utilized by the frame's cells. Initially, the sugars withinside the meals you consume are digested into the easy sugar glucose, a monosaccharide.

Recall that glucose is the sugar produced through the plant for the duration of photosynthesis. The important feature of easy carbohydrates is to offer the frame electricity.

An example is a goat and plant food chain.

What is food energy?

Food energy is chemical electricity that animals (such as humans) derive from their meals to maintain their metabolism, such as their muscular activity. Most animals derive maximum in their electricity from cardio respiration, specifically combining the carbohydrates, fats, and proteins with oxygen from air or dissolved in water.

Thus it is cleared from the above.

Species that evolved in coral reef habitats always stay in those habitats. Coral reefs have much biodiversity, but most species that live there migrated from other habitats. Most organisms that live in coral reef habitats are zooxanthellae. More new species have evolved in coral reef habitats than in most other types of habitats.

Answers

Answer:

Most organisms that live in coral reef habitats are zooxanthellae.

Explanation:

zooxanthellae are the single-celled dinoflagellates that lives in mutual relationship with corals, jellyfish, and nudibranchs. These organisms have a mutualistic relationship between zooxanthellae and corals. Coral produces carbon dioxide and water in the process of cellular respiration while on the other hand, the zooxanthellae use this carbon dioxide and water to carry out photosynthesis for making their own food like plants so both the organisms get benefit from one another.

An organism’s appearance is its phenotype. Describe the offspring’s phenotype.

Answers

Answer:

the offsprings’ phenotype will be based on the expression of the combination of genes inherited from the parents.

Explanation:

As children we inherit both from our parents. This means that the genotype from the allels inherited from both parents. Phenotype is how genes are exoressed. If you inherit a blue-eyed gene from one parent and a brown-eyed gene from the other, your genotype is Brown/blue. How the genes are expressed is your phenotype, and in this simple model, you will have brown eyes. This is because “brown” is a dominant trait for eye color, and blue is recessive. If you inherited a blue eyed gene for eye color from both parents, your phenotype of this genetic trait will be blue eyes. Eye color is not as simple as this. There are several different genes involved in eye color, and although brown is a dominant trait, there are many variations of eye color, even in those big brown eyes.
