Answer:

number of chromosmes are reduced at anaphase.

Explanation:

At anaphase of cell division, chromosomes that are aligned on the metaplate are pulled apart by kinetchore microtubules connected at the centromere of each chromosome reducing the number of chromosomes by half.

Answer: Chloroplasts.

Explanation:

Plant cells have several structures not found in other eukaryotes. In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.What Is the Origin of Chloroplasts?Like mitochondria, chloroplasts likely originated from an ancient symbiosis, in this case when a nucleated cell engulfed a photosynthetic prokaryote. Indeed, chloroplasts resemble modern cyanobacteria, which remain similar to the cyanobacteria of 3 million years ago. However, the evolution of photosynthesis goes back even further, to the earliest cells that evolved the ability to capture light energy and use it to produce energy-rich molecules. When these organisms developed the ability to split water molecules and use the electrons from these molecules, photosynthetic cells started generating oxygen — an event that had dramatic consequences for the evolution of all living things on Earth (Figure 1).although they are much smaller. (Mitochondrial genomes are even smaller than the genomes of chloroplasts.) Coding sequences for the majority of chloroplast proteins have been lost, so these proteins are now encoded by the nuclear genome, synthesized in the cytoplasm, and transported from the cytoplasm into the chloroplast.What Is the Function of Chloroplast Membranes?Like mitochondria, chloroplasts are surrounded by two membranes. The outer membrane is permeable to small organic molecules, whereas the inner membrane is less permeable and studded with transport proteins. The innermost matrix of chloroplasts, called the stroma, contains metabolic enzymes and multiple copies of the chloroplast genome.Chloroplasts also have a third internal membrane called the thylakoid membrane, which is extensively folded and appears as stacks of flattened disks in electron micrographs. The thylakoids contain the light-harvesting complex, including pigments such as chlorophyll, as well as the electron transport chains used in photosynthesis (Figure 2).

Answer:

b) Ribosomes and mitochondria

Explanation:

Ribosomes and mitochondria is an example of two organelles that both animal and plant cells have in common. Hence, the option (b) is the correct answer.

The stages of the virus replication cycle that are shared by the majority of productive viral infections are attachment, penetration, uncoating, replication, assembly, and release. Hence (a) is the correct option.

The process through which an infection results in disease is known as pathogenesis. Virus implantation at the point of entry, local replication, dissemination to target organs (disease sites), spread to sites of virus shedding into the environment, and so forth are some of the pathogenic mechanisms of viral disease. A pathogen must effectively complete all four of the pathogenesis processes or stages in order to produce disease: exposure (contact), adhesion (colonisation), invasion, and infection.

Answer:

Brain, heart, lungs, liver, kidney

Explanation:

Caffeine does not bioaccumulate in our body but heavy metals like mercury and lead can accumulate because caffeine are fat-soluble and broken down into simpler substances and used by the body whereas heavy metals are not fat-soluble and also essential for our body to function normally but when these heavy metals are very in concentration it accumulated in our body and causes several problems in our body organs. These heavy metals accumulation occurs in the organs such as brain, heart, lungs, liver and kidney where it cause problems.

Caffeine is in organic molecules that are metabolized by the liver. Heavy metals are atoms that cannot be broken down. They can be sequestered in the bones or in fatty tissue (with methylmercury) and have a long residence time in the body.

These toxins are stored in the human brain, heart, lungs, liver, and kidney.

The word-heavy metal directs to any metallic chemical element that has a relatively high density and is toxic at low concentrations.

Examples of heavy metals include mercury (Hg), cadmium (Cd), arsenic (As), etc.

Thus, Heavy metals are atoms that cannot be broken down.

The "what" pathway is also known as the ventral pathway, and the "where/how" pathway is also known as the dorsal pathway.

In the field of neuroscience, the visual processing system in the brain can be divided into two main pathways: the ventral pathway and the dorsal pathway. These pathways are responsible for processing different aspects of visual information.

The ventral pathway, often referred to as the "what" pathway, is primarily involved in object recognition and identification. It processes information about the shape, color, and identity of objects in the visual field. This pathway helps us recognize and distinguish various objects in our environment.

On the other hand, the dorsal pathway, also known as the "where/how" pathway, is primarily involved in spatial awareness, motion perception, and guiding actions based on visual information. It processes information about the location, movement, and depth of objects in the visual field. This pathway helps us determine the spatial relationships between objects and guides our motor actions, such as reaching and grasping.

So, the "what" pathway (ventral pathway) focuses on object recognition and identification, while the "where/how" pathway (dorsal pathway) focuses on spatial awareness and action guidance.

In the context of behavioral psychology, shaping refers to the gradual process of teaching a new behavior by reinforcing successive approximations of that behavior.

In other words, shaping involves reinforcing behaviors that are closer and closer to the target behavior, until the target behavior itself is achieved.

Shaping is related to operant conditioning in that it is a technique used within the framework of operant conditioning to teach new behaviors.

Operant conditioning involves the use of rewards and punishments to modify behavior, and shaping is one of the techniques that can be used to shape and reinforce new behaviors.

What is shaping and how it is related to operant conditioning ?

For example, let's say a trainer wants to teach a dog to fetch a ball. At first, the trainer might reward the dog for simply showing interest in the ball.

Then for moving toward the ball, then for picking it up in its mouth, and so on, until the dog is reliably fetching the ball on command.

By reinforcing each successive approximation of the target behavior, the trainer is using shaping to gradually teach the dog a new behavior, and this process is an example of operant conditioning.

Explanation:

Energy is stored and released from the ATP molecule through the breaking and forming of high-energy phosphate bonds. Pigment molecules, such as chlorophyll, contribute to ATP production by absorbing light energy and moving electrons in photosynthesis.

The energy storage and release process in the ATP molecule is as follows:

1. ATP, or adenosine triphosphate, is composed of an adenosine molecule bound to three phosphate groups.

2. Energy is stored in the high-energy phosphate bonds between the phosphate groups.

3. When a cell needs energy, ATP undergoes hydrolysis, where one phosphate group is removed, forming ADP (adenosine diphosphate) and inorganic phosphate (Pi). This reaction releases energy for cellular processes.

4. To replenish ATP levels, ADP is phosphorylated, with the addition of inorganic phosphate, using energy from cellular respiration or photosynthesis.

Regarding pigment molecules, they are involved in the process of photosynthesis in plants and some microorganisms, which ultimately helps to produce ATP. Pigment molecules, such as chlorophyll, absorb light energy and transfer excited electrons through an electron transport chain.

This transfer of electrons generates a proton gradient that drives the production of ATP via a process called chemiosmosis.

Correction of Nearsightedness (Myopia) using a Diverging Lens

Nearsightedness, also known as myopia, is a common refractive error of the eye that affects a person's ability to see distant objects clearly. In myopia, the basic optical problem lies in the excessive focusing power of the eye, causing the focal point to fall in front of the retina instead of directly on it. This results in distant objects appearing blurry or out of focus.

To correct nearsightedness, a diverging lens is used. A diverging lens is a concave lens that causes light rays to spread out or diverge. When placed in front of the nearsighted eye, the diverging lens helps to decrease the focusing power of the eye by further diverging the incoming light rays before they enter the eye. This adjustment allows the focal point to move backward, aligning it with the retina, and allowing distant objects to be seen more clearly.

To remember which type of lens corrects this defect, we can associate the terms "nearsighted" and "diverging." Since a diverging lens spreads out light rays, it helps to correct the focusing problem associated with nearsightedness. The idea of "diverging" aligns with the goal of moving the focal point backward, away from the eye, and closer to the retina.

In summary, nearsightedness (myopia) is corrected by using a diverging lens, which reduces the focusing power of the eye and allows the focal point to align with the retina. The association between "nearsighted" and "diverging" can help remember that a diverging lens is the appropriate choice for correcting this particular refractive error.

The principle function of fibrocartilage in the spine is to provide support, stability, and flexibility to the vertebral column.

fibrocartilage is a type of cartilage found in the body that has both collagen fibers and cartilage cells. It is found in areas that require both support and flexibility, such as the intervertebral discs in the spine.

The intervertebral discs are made up of fibrocartilage and act as shock absorbers between the vertebrae, allowing for movement and cushioning the spine. They help distribute the forces applied to the spine during movement and prevent excessive compression or damage to the vertebrae.

In addition to providing support and cushioning, fibrocartilage in the spine helps maintain the spacing between the vertebrae, allowing for proper alignment and preventing bone-on-bone contact. This is important for the overall function and health of the spine.

Overall, the principle function of fibrocartilage in the spine is to provide support, stability, and flexibility to the vertebral column. It plays a crucial role in maintaining the structural integrity and function of the spine.

Hey there,

The answer is A.

This is because the crust is broken into parts called plates and these plates collide with each other or separate from each other or slide past each other.

They move because they sit on top of semi molten rock in the mantle. The semi molten rock moves due to convection currents which is heated up by the core.

It’s is not option B because it does not have u form thickness through out it. For eg the continental crust is 60 km thick while the oceanic plates are wonly 10km thick.

It is not C as the mantle is semi molten not solid.
