What structures have parasite worms lost? What structures/organs are expanded?

Answers

Explanation:

Something that is lacking, is a circulatory system. Instead of a typical circulatory system flatworms exchange oxygen with the air outside through diffusion. This is the process by which gases will pass through a membrane from an area of high concentration to an area of low concentration.

The structure of the plasma membrane is often explained using the "Fluid Mosaic Model". In this model, the term "fluid" best refers to which of the following?

Group of answer choices

What regulates breathing rate and how does the body sense when to breath?

Answers

Answer:

Involuntary respiration is controlled by the respiratory centers of the upper brainstem (sometimes termed the lower brain, along with the cerebellum). This region of the brain controls many involuntary and metabolic functions besides the respiratory system, including certain aspects of cardiovascular function and involuntary muscle movements (in the cerebellum).

Explanation:

The respiratory centers contain chemoreceptors that detect pH levels in the blood and send signals to the respiratory centers of the brain to adjust the ventilation rate to change acidity by increasing or decreasing the removal of carbon dioxide (since carbon dioxide is linked to higher levels of hydrogen ions in blood).

5. How does low biodiversity impact the stability of a tundra ecosystem?

4. Who else benefits from polar bear hunting?

3. Describe a polar bears niche.

1. How do tundra ecosystems in biodiversity compare in biodiversity to other types of ecosystems?

Answers

Answer: 5. Biologically numerous groups also are much more likely to include species that confer resilience to that ecosystem due to the fact as a network accumulates species, there may be a better risk of anybody of them having developments that permit them to conform to a converting environment.

3. The polar bear's ecological niche is that of a specialized predator of seals. When there are numerous seals around, adult polar bears will usually devour the blubber (fat) and pores and skin of the seals, which gives an awesome supply of energy. Younger bears will devour beef because the protein allows them to grow.

1. How do tundra ecosystems in biodiversity compare in biodiversity to other types of ecosystems?

Answer: Ecosystems in the arctic tundra are an example of those where there are fewer species overall than in other kinds of ecosystems.

2. What is a niche?

Answer: a role that a species plays in the ecosystem

3. Describe a polar bear's niche.

Answer: Some animals gain from polar bears' hunting of seals. A polar bear will leave behind significant portions of a seal after eating all of it. In tundra environments, these leftovers are a source of food for Arctic foxes, gulls, and other birds, particularly during the chilly winter months when there is nothing to eat. Healthy polar bear populations can have a good effect on other species' numbers, such as those of birds or Arctic foxes. Numerous other species are harmed when polar bear populations drop.

4. Who else benefits from polar bear hunting?

Answer: Arctic foxes, gulls, and other birds

5. How does low biodiversity impact the stability of a tundra ecosystem?

Answer: The species that provide resilience to an ecosystem are therefore far more likely to be found in biologically diverse groups because as a network accumulates species, there may be a greater chance that any one of them will have evolved to adapt to a changing environment.

Why do mutations code proteins?

Answers

Answer:

A nonsense mutation is a genetic mutation in a DNA sequence that results in a shorter, unfinished protein product. DNA is a chain of many smaller molecules called nucleotides. During protein formation, DNA (or RNA) nucleotide sequences are read three nucleotides at a time in units called codons, and each codon corresponds to a specific amino acid or stop signal (stop codon).

Earth has gone through many cycles of ice ages followed by periods of warmer climate. How might these cycles be related to patterns of solar output and patterns of change in Earth’s motion in space?

Answers

Answer:

They both go back and forth, such as the climate going from hot to warm, and the tectonic plates of the earth going from closed 300 million years ago to spreading far apart now.

Both of them oscillate, as seen by the earth's tectonic plates, which went from being tightly packed 300 million years ago to spreading widely at the moment.

What is tectonic plate?

Tectonic plate is defined as the lithosphere is made up of sections or parts of the upper mantle and crust of the earth. Starting around 4 billion years ago, cooler parts of the Earth's crust were forced downward into the warmer upper mantle, damaging and weakening the surrounding crust. According to the authors, this cycle repeated itself until the weak spots established plate borders.

Slow variations in the Earth's orbit start and conclude these ice eras. However, variations in CO2 concentrations in the atmosphere also play a significant role in driving both cooling at the start of ice ages and warming at their end. During the last ice age, the average global temperature was around 4C lower than it is now.

Thus, both of them oscillate, as seen by the earth's tectonic plates, which went from being tightly packed 300 million years ago to spreading widely at the moment.

how many chromosomes are there in human ovum​

Answers

Answer:

23 chromosomes

Unlike all the other cells in a human body which are diploid, human sex cells are haploid. That means that both sperm cells and ova are haploid; containing only 23 chromosomes.

Explanation:

have a good day!

(─‿─)

The chromosomes in egg and sperm cells have just 23 chromosomes each.

What is gamete?

Male gametes are termed sperm, while female gametes are called "ova." Gametes are an organism's reproductive cells, also referred to as "gender cells." Since gametes are haploid cells, each chromosome is present in one copy per cell.

Unfertilized reproductive cells are called gametes. A zygote is an egg that has been fertilized. Gametes are always haploid cells since they are a byproduct of meiosis.

Zygote is a diploid structure because it results from the fusing of a male and female haploid gamete.

Similar to a sperm, an egg has 23 chromosomes total, which is half the number found in a normal cell.

The resultant embryo will therefore have the typical 46 chromosomes in total after an egg and sperm join during fertilization.

Thus, there are 23 chromosomes in human ovum.

Answers

Answer:

b) Forming zygots

Explanation:  

A zygote can be defined as a eukaryotic cell formed by the fusion of gametes during sexual reproduction. In general, a zygote is a diploid (2n) cell produced by the fusion of two haploid (n) gametic cells (eg., in mammals, sperm and egg cells). In multicellular organisms, the zygote is the first stage of development, which will give rise to an adult organism as it divides and grows. A zygote cell can be considered as a pluripotent stem cell because it differentiates into all cell types.

What would happen to Earth's climate if we had no moon, and why?

Answers

Answer:

The tilt creates what we know as seasons and changing weather. Without the pull of the moon, this tilt would change.

Explanation:

Either the tilt would become extreme, leading to extreme and severe seasons, or the tilt would decrease, and we would see almost no seasons at all. The moon influences life as we know it on Earth.

Answer: Because It is the pull of the Moon's gravity on the Earth that holds our planet in place. Without the Moon stabilising our tilt, it is possible that the Earth's tilt could vary wildly. It would move from no tilt (which means no seasons) to a large tilt (which means extreme weather and even ice ages).

The average molecular weight of proteins encoded in the human genome is about 50,000. A few proteins are very much larger than this average. For example, the protein called titin, which is made by muscle cells, has a molecular weight of 3,000,000. Estimate how long it will take a muscle cell to translate an mRNA coding for an average protein and one coding for titin. The average molecular mass of amino acids is about 110 daltons. Assume that the translation rate is two amino acids per second.

Answers

Answer:

13,636 seconds = 227.3 minutes = 3.79 hours

Explanation:

The titin protein has a molecular weight of 3,000,000 daltons, while the average molecular mass of one amino acid is 110 daltons, so it is expected that this protein is composed of 27,273 amino acids (3,000,000 daltons/110 daltons = 27,272.72). Moreover, and since the translation rate is two amino acids per sec, it is expected that the protein will be synthesized in approximately 3.79 hours (27,272.72/2 = 13,636 seconds = 227.3 minutes = 3.79 hours).

Cystic fibrosis is a recessive genetic disease caused by a mutation in the gene that encodes the CFTR protein, which transports chloride ions in and out of cells. Some populations have a relatively high rate of cystic fibrosis carriers, possibly because the mutation protects against severe dehydration in diseases like cholera or typhoid. What concept does this best illustrate?
A: Polygenic traits
B: Genetic drift
C: Pleiotrophy
D: Heterozygote advantage

Answers

its letter b the genetic drift because it is mechanism of evolution in which allele frequencies of a population change over generation due to chance.

Cystic fibrosis is a recessive genetic disease that encodes the CFTR protein, but some populations have a relatively high rate of cystic fibrosis carriers, which protects against severe dehydration and is an example of the heterozygote advantage that is present in Option D.

What is the heterozygote advantage?

When the gene is present in a heterozygote state, the gene product benefits the individual rather than harming him or her, as in sickle cell anemia and cystic fibrosis. In sickle cell anemia, the heterozygote state protects the person from malaria, and in cystic fibrosis, it protects the person from dehydration.

Hence, Cystic fibrosis is a recessive genetic disease that encodes the CFTR protein, but some populations have a relatively high rate of cystic fibrosis carriers, which protects against severe dehydration and is an example of the heterozygote advantage that is present in Option D..

The given image shows the relationship between different structures in a plant and their functions.

What are the structures of plants and their functions?

There are various plant parts, each with its unique characteristics and functions to do. Each one of them plays a vital role in maintaining a healthy ecology and environment.

The parts of the plant include

Roots: The most crucial component of a plant is its roots. They are located underground and make up a plant's root system. They are responsible for holding the plant in place with the soil. They serve as an anchor that the plant uses to keep itself steady. By soaking up water, nutrients, and minerals from the soil, they also control the health of the plant. A plant can grow as a result of these. Additionally, they keep food supplies for later use.Stems: It is the second most crucial component. It rises above the ground, starts out green, and eventually turns brown as it gets older. They consist of leaves, fruits, and flowers and sustain the plant's stalk system. They support the framework and structure of the plantLeaves: Chlorophyll, which is responsible for the synthesis of plant food, can be found there. To prepare the food, it makes use of water, carbon dioxide, and sunlight. A leaf is further divided into three main parts: the petiole, leaf base, and lamina.Flowers: There are certain plants that do not have flowers. They have a vibrant, peaceful aesthetic. They are the plant's reproductive system. Petals, sepals, stamens, and pistils are its four main constituent components.Fruits: Fruit production is carried out by flowering plants. After fertilization, the fully developed ovary transforms into a fruit. They develop into a seed first, then a fruit.
