in humans how many chromosomes in daughter cells​

Answer:

These cells use active-transport systems in the apical domains of their plasma membranes to take up dietary sugars and amino acids from the lumen of the intestine. The uptake of glucose, for example, is carried out by a transporter that coordinately transports two Na+ and one glucose into the cell

Explanation:

If the cell is placed in an environment where the solute concentration is greater than the cell's cytoplasm, the cell will shrink and water will move out of a cell.

If a cell is placed in a solution that has higher levels of solute, this means that the water will move out of the cell as a result of osmosis. Osmosis is the movement of water molecules from a higher concentration to a lower concentration.

When the water will move out of a cell, the cell will shrink.

In order for maintaining a balance, the cell and the solution in which it is kept shall maintain equilibrium.

The process by which accumulated adaptations result in superficially similar animals derived from different stock is called convergent evolution.

Convergent evolution is a biological phenomenon where different species, which are not closely related, independently evolve similar traits or adaptations in response to similar environmental pressures. These adaptations may include physical or behavioral characteristics that enable the organisms to survive and thrive in their respective environments. Although the organisms may have different ancestral origins, convergent evolution results in them sharing similar features that allow them to perform similar functions. For example, wings have evolved independently in birds, bats, and insects, all of which use them for flight, despite having different underlying anatomical structures.

Answer: The primary function of pyloric valve is to pass the food from stomach to the top of small intestine

Explanation: The pyloric sphincter at the bottom of the stomach is a muscular valve which helps to transfer food from stomach to small intestine.

Stomach is a muscular sac about the size of a small melon . once the stomach breaks the complex and strong muscular contractions , food is pushed towards the pyloric valve . This valve leads to the upper portion of your small intestine, a segment known as the duodenum.

The evolution of crotamine involves gene duplication and recruitment of a non-toxic gene into the venom gland of snakes, followed by subsequent mutations that confer toxicity and select for its use in prey capture.

Crotamine is a small basic peptide found in the venom of some South American rattlesnakes. Studies have shown that crotamine evolved through gene duplication and recruitment of a non-toxic gene coding for a skeletal muscle protein. The duplicated gene then underwent multiple mutations and became a new gene coding for crotamine.

The process of gene duplication and recruitment is a common mechanism in the evolution of venomous animals, as it allows for the emergence of new toxins from non-toxic genes already present in the genome. This process involves the duplication of a gene, followed by mutations in one copy that give rise to a new function, such as a toxin. The original gene can then retain its original function or acquire a new one, resulting in the emergence of new traits that can provide an adaptive advantage.

Therefore, the evolution of crotamine in snake venom is an example of how gene duplication and recruitment can lead to the emergence of new and diverse toxins, providing a selective advantage in the context of predator-prey interactions.

Answer: Products of respiration:

Glucose and oxygen

Carbon dioxide and water (and ATP)

A complicated and intriguing substance, soil is. The majority of it is composed primarily of compost, or other items that have decomposed. The earth absorbs the leaves that fall from the trees (etc.). Along with this, there are numerous types of clays (basically powdered rock), sands (basically crumbled rock), as well as other minerals and organics, byproducts of worm, fungus, and bacterium metabolism, and so on.

We lose much too much soil due to erosion and deforestation, which is a great shame (which leads to more erosion).

The different nutrients that plants "feed" from it include nitrogen, which certain plants require from the soil while others may obtain from the air. They do this by soaking up water and the dissolved minerals through their roots and into their systems.

The majority of what makes a plant a plant, just like the majority of what makes a tree a tree, comes from the air.

Plants absorb carbon dioxide from the atmosphere and waste oxygen in the process. Their cell walls are made of carbon from the carbon dioxide.

For instance, cellulose is (C6 H10 O5)n, much like the wood in your door, table, apartment, etc. The carbon dioxide that the plant "breathes" provides the six carbon atoms in the molecule.

In connection with this, trees physically "suck" carbon dioxide out of the air, which is why they help us slow down climate change. And for this reason, burning fossil fuels worsens climate change by reintroducing gases like carbon dioxide and others into the atmosphere.

Some form of early Homo is estimated to have evolved into Homo erectus around 1.7-2 million years ago, option B is correct.

Homo erectus is believed to have evolved around 1.7-2 million years ago based on fossil evidence and dating methods. Fossil discoveries, such as the famous Nariokotome Boy skeleton found in Kenya, provide crucial insights into the anatomy and characteristics of Homo erectus. These fossils, along with other archaeological and genetic evidence, suggest that Homo erectus was the first hominin species to exhibit significant anatomical and behavioral differences from earlier hominins.

The emergence of Homo erectus marked a significant milestone in human evolution, as this species had a larger brain size, more advanced tool-making abilities, and potentially even the ability to control fire.

Red blood cells are produced more frequently than the other types, the body produces them every second, hence option 2 is correct.

Medication that promotes the formation of RBCs: Erythropoietin is a hormone that is made in the liver and kidneys and stimulates the production of RBCs in the bone marrow. Some types of anemia can be treated with erythropoietin.

In order to replace those red blood cells that eventually deteriorate and die, red blood cells are continuously created in the bone marrow. A red blood cell has a lifespan of roughly 120 days on average. Anemia and shortness of breath result from a large drop in the number of red blood cells.

A  one-minute exposure to light in the middle of the dark period disrupts the required uninterrupted darkness for short-day plants and resets their internal clock, preventing them from flowering. This response is due to the specific light sensitivity and photoperiodic requirements of short-day plants.

If a short-day plant receives a one-minute exposure to light in the middle of the dark period rather than continuous darkness, it will not flower.


Short-day plants, also known as long-night plants, require a certain period of darkness to induce flowering. These plants initiate flower formation when the duration of uninterrupted darkness exceeds a critical threshold, typically around 12-16 hours. In the absence of this continuous darkness, the plant's internal processes and hormone production are not triggered, leading to the inhibition of flowering.

When a short-day plant is exposed to a one-minute exposure to light in the middle of the dark period, it disrupts the required uninterrupted darkness and resets the internal clock of the plant. This exposure to light interrupts the plant's perception of the long night and signals that it is not yet time to initiate the flowering process. Consequently, the plant does not produce flowers.

To better understand this phenomenon, imagine a short-day plant as having an internal timer that keeps track of the duration of darkness it experiences. When the timer reaches the critical threshold, the plant begins to flower. However, any interruption of darkness, even for a short duration like one minute, resets the timer back to zero, effectively delaying the flowering process.
