In case of asexual reproduction, the new organism generated is genetically identical to its parent. b. In sexual reproduction, offspring's genetic make-up differs from parents' due to recombination of both parents' DNA.

A diploid zygote is created during sexual reproduction when two haploid gametes formed during meiosis combine. Each parent contributes half of a child's genetic makeup. Therefore, even if they may resemble their parents, they are not exactly like them.

Although there may be a few little distinctions, generally speaking, our parents and siblings are connected to us in the same way.

The ecosystem, biodiversity, and carrying capacity are interrelated as everything is related to the living diversity present in an ecosystem.

An ecosystem is a group of living things that communicate with one another. It is the geographic area that contains plants, animals, and other biotic and abiotic factors.

The quantity of biodiversity that can be sustained in a region is known as its carrying capacity. An ecosystem is a group of living things that communicate with one another. The biodiversity of plant and animal species is known as its biodiversity.

A space's carrying capacity reveals how long and how much of an ecosystem it can support, which in turn reveals how much biodiversity is possible.

Thus, because everything is connected to the living diversity present in an ecosystem, the ecology, biodiversity, and carrying capacity are all interconnected.

When a new mutation occurs in a somatic cell of a sexually reproducing organism, it will not be inherited to the offspring. The germ line cells contribute to the offspring, not the somatic cells.

Genes pass from parents to offspring, and this is called inheritance. As a result, offspring bear some resemblance to their parents. In animals, there are two types of cells: the somatic cell and the germline cell.

The somatic cell is present throughout the body and doesn't contribute to inheritance. Germ line cells present in the reproductive organ undergo meiosis and form gametes that contribute to the offspring.

Hence, no offspring will inherit the mutation of the somatic cell.

Answer:

d. G1 → S → G2 → M.

Explanation:

The eukaryotic cell cycle consists of several phases, each with specific activities and events. The correct order is as follows:

G1 phase (Gap 1 phase): This is the first growth phase where the cell grows, carries out its normal functions, and prepares for DNA replication.

S phase (Synthesis phase): During this phase, DNA replication occurs, resulting in the duplication of the cell's genetic material.

G2 phase (Gap 2 phase): In this phase, the cell continues to grow and prepares for cell division. It checks for DNA errors and ensures proper replication.

M phase (Mitosis phase): The M phase includes several stages such as prophase, metaphase, anaphase, and telophase, culminating in cell division (cytokinesis) where two daughter cells are formed.

Therefore, the correct order is G1 → S → G2 → M.

The muon travel before it decayed, if there were no time dilation is approximately 92.4 m

The muon is a subatomic particle that only lasts for 2.2 μs. However, if there were no time dilation, it would be possible to calculate how far it could travel before decaying. In order to do so, one would need to know the muon's speed, which can be found using the Lorentz factor formula:γ = 1 / sqrt(1 - (v/c)^2)where v is the muon's speed and c is the speed of light.

Once the speed is found, the distance it can travel is simply the product of its speed and its lifetime:distance = speed x lifetime

For a muon travelling at 0.99c, its Lorentz factor would be 7.09.

Therefore, its speed would be v = 0.99c / 7.09 = 0.14c.

Using its lifetime of 2.2 μs, the distance it can travel is:distance = 0.14c x 2.2 μs = 92.4 m. In conclusion, if there were no time dilation, a muon travelling at 0.99c would travel approximately 92.4 m before decaying.

As per the details given, using probability there are 8 possible combinations of hats, belts, and ties.

You need to know the entire number of possible combinations and the total number of positive outcomes in order to determine the likelihood of a certain arrangement of hats, belts, and ties happening.

You may get the total number of combinations by multiplying the number of options for each item (hats, belts, and ties), as each has two options.

In this instance, you have two hat options (red or black), two belt options (blue or white), and two tie possibilities (DNA or 2n). Consequently, there are the following combinations in all:

2 (options for hat) * 2 (options for belt) * 2 (options for tie) = \(2^3\) = 8

Thus, there are 8 possible combinations of hats, belts, and ties.

Answer:

Proteins play a crucial role in regulating the distribution of water in the body. Specifically, proteins in the blood plasma help to maintain the balance of fluids between the blood vessels and the surrounding tissues by creating a pressure gradient that keeps fluids from leaking out of the vessels. When the concentration of proteins in the blood plasma is much lower than usual, as is the case in individuals with kwashiorkor, this pressure gradient is disrupted, and fluids begin to leak out of the blood vessels and accumulate in the surrounding tissues. This can result in swelling, or edema, in various parts of the body, including the feet, legs, and belly.

Answer:

The low concentration of proteins in the blood plasma causes a decrease in the osmotic pressure of the blood. This decrease in osmotic pressure causes water to move from the blood into the tissues, leading to an accumulation of tissue fluid and swelling.

In reality, a growing corpus of research demonstrates that synesthesia is more prevalent in creative people.  

That some of the greatest thinkers, including Hockney, Kandinsky, and Nabokov, were synesthetes. Synesthetes, who make up about 4% of the population, are individuals whose senses blend in a way that resembles cross-wiring in the brain. The name synesthesia means "union of the senses." According to estimates, 3 to 5 percent of people suffer from synesthesia, and women are more likely than males to develop the condition. Synesthesia is a neuropsychological condition in which the activation of one sense results in the automatic perception of a different sense. Between 2 and 5 percent of the general population are thought to be affected by the hereditary feature known as synesthesia.
