Answer:

d. hyperthyroidism

Explanation:

Hyperthyroidism is a condition that occurs when the thyroid gland in our body secretes too much of the thyroxin hormone. Thyroid gland is a butterfly shaped gland that is located in our neck and it produces the hormone called thyroxin. Excess production of thyroxin leads to a condition named hyperthyroidism.

A person's metabolism increases when he or she is suffering from hyperthyroidism. One's weight is lost but the appetite increases. Other symptoms are extreme fatigue, irritability, heart palpitations, sweating and puffy eyes.

Thus in the context, Ms. Jones is suspect to have hyperthyroidism as she she is showing all the above symptoms.

This is a problem in the field of ecology.

The problem of quagga mussels in the lake is an ecological issue that requires scientific assessment and management.

It falls under the discipline of ecology, which studies the relationships between organisms and their environment.

Ecologists investigate the impacts of invasive species on the ecosystem and devise strategies to control their spread and minimize their effects.

In this case, scientists will need to examine the size of the quagga mussel population, their distribution, and their ecological interactions with native species.

They will also need to recommend measures to prevent further introduction of quagga mussels and to manage their population growth, such as using chemical treatments or biological controls.

The organisms that feed on dead and decaying matter are called Saprotrophs.

An organism that feeds on dead and decaying organic matter is called a saprotroph. These organisms are heterotrophic, which means that they obtain their food from other sources. They are important in the ecosystem because they break down dead organic matter and recycle it back into the soil, making nutrients available to other living organisms

Answer:

A. Saprotrophs

Explanation:

Saprotrophs are organisms that obtain their nutrients by feeding on dead and decaying matter. They play a crucial role in the ecosystem by decomposing organic material and recycling nutrients back into the environment.

These organisms secrete enzymes that break down complex organic compounds into simpler substances, such as sugars and amino acids, which they can absorb and utilize for their own growth and energy needs. Examples of saprotrophs include fungi (such as mushrooms and molds) and certain bacteria.

Unlike autotrophs, which can produce their own food through photosynthesis or chemosynthesis, saprotrophs rely on external sources of organic matter for their nutrition. They actively decompose dead plants, animals, and other organic materials, aiding in the process of nutrient recycling and decomposition.

Heterotrophs, on the other hand, are a broader category of organisms that obtain their nutrients by consuming other living or dead organisms. This includes saprotrophs, as well as other types of organisms such as herbivores, carnivores, and omnivores.

Parasites, meanwhile, are organisms that live in or on other organisms, known as hosts, and obtain their nutrients from the host while causing harm or damage to it. Unlike saprotrophs, parasites typically rely on a living host for their sustenance rather than feeding on dead and decaying matter.

Viruses spread by infecting cells and replicating within them. There are several ways that viruses can spread from one person to another:

Direct contact: Viruses can be spread through direct contact with an infected person, such as through shaking hands or hugging.

Indirect contact: Viruses can also be spread through indirect contact, such as by touching a surface or object that has been contaminated with the virus and then touching one's face, mouth, or eyes.

Respiratory droplets: Some viruses, such as the virus that causes COVID-19, are spread through respiratory droplets that are produced when an infected person talks, coughs, or sneezes. These droplets can land in the mouths or noses of people who are nearby or be inhaled into the lungs.

Sexual contact: Some viruses, such as HIV and herpes, are spread through sexual contact.

Overall, viruses can spread through a variety of means, and the specific method of transmission can depend on the specific virus and the mode of infection.

Meiosis occurs in two main phases: Meiosis I, which involves the separation of homologous chromosomes, and Meiosis II, which involves the separation of sister chromatids.

Meiosis is a complex cellular process that occurs in sexually reproducing organisms to produce gametes (sperm and eggs) with half the number of chromosomes as the parent cell. It consists of two successive divisions, known as Meiosis I and Meiosis II, each with distinct phases.During Meiosis I, the cell goes through the following phases: prophase I, metaphase I, anaphase I, and telophase I. The key events during this phase include pairing of homologous chromosomes (synapsis) and exchange of genetic material between them (crossing over) in prophase I. This is followed by the alignment of homologous chromosomes along the equator of the cell in metaphase I, their separation and migration towards opposite poles in anaphase I, and finally the formation of two haploid daughter cells in telophase I.

Meiosis II, which is similar to mitosis, follows Meiosis I without any DNA replication. The phases of Meiosis II include prophase II, metaphase II, anaphase II, and telophase II. In prophase II, the nuclear envelope breaks down, and the chromosomes condense. In metaphase II, the chromosomes align along the equator of the cell. In anaphase II, the sister chromatids separate and move towards opposite poles. Finally, in telophase II, the nuclear envelope reforms, and four haploid daughter cells are produced.

As we know active transport implies the movement of chemical compounds/ions across the membrane using energy (ATP) to do so. One of the most common examples of active transport is the kown sodium-potassium pump, a mechanism that is found in all animal life forms. Another example is plant root cells, these need to absorb mineral salts from the ground, however, these salts tend to be very diluted so active transport allows these salts to be absorbed by the plants against the concentration gradient.

Answer:

Rocks of varying sizes.

Explanation:

Billions of asteroids between two main groups of planets in the solar system are rocks of various sizes.

The solar system's asteroid belt is a torus-shaped area about halfway between Jupiter and Mars orbits. It has a large number of asteroids or minor planets.

Which are solid bodies with erratic shapes and sizes that are smaller than planets. It seems that one or more planets may have developed in the zone between Mars and Jupiter, but Jupiter's gravity kept tearing everything apart.

The material in this area was never able to create a single planet, just asteroid-sized particles.

Therefore due to various solid particles between the two main planets, there is a belt of asteroids.

Most articles pass right through the atom, this means that most of the atom is an empty space.

An atom is described as a particle that consists of a nucleus of protons and neutrons surrounded by a cloud of electrons.

Protons and neutrons make up the core nucleus of an atom, which is encircled by an electron cloud. In relation to the size of the atom as a whole, the nucleus is exceedingly small.

As a result, the electrons surrounding the nucleus are the primary target of interactions when particles or even light pass through an atom. The majority of the atom's remaining space, which includes the nucleus, is vacant.

Explanation:

A tiny electric message moves through a long part of a brain cell called the axon. When a message goes to the end of a nerve, it sends chemicals called neurotransmitters. These substances move through a tiny gap and attach to special parts of another nerve cell's outer covering.

Messages called impulses are sent from one nerve cell to another through a connection called a synapse. This process is called synaptic transmission. Synapses are connections between nerve cells or between nerve cells and other cells, like muscles or glands.

The neuron sending the signal is called the presynaptic neuron. When a signal travels down a nerve cell, it causes little sacs called vesicles to release chemicals called neurotransmitters.

The functions of rough endoplasmic reticulum and Golgi body are related because A .proteins synthesised by the rough endoplasmic reticulum are modified by the Golgi body

Both the Golgi body and the rough endoplasmic reticulum (RER) are important in the production and processing of proteins. Ribosomes, which are found throughout the RER and produce proteins, are subsequently transferred into the lumen of the RER for further processing. These proteins are delivered by the RER to the Golgi body, where they are modified, sorted, and packaged for distribution to various locations inside cell or for secretion beyond it.

The Golgi body is in charge of altering proteins that the RER has synthesised. This might entail altering amino acids by adding or removing functional groups, adding carbohydrate chains to proteins to create glycoproteins, or chopping off pieces of proteins to create smaller peptides.

Answer:

Explanation:

In general, otters play a crucial role in maintaining the health of kelp forests. They are considered a keystone species because they feed on sea urchins, which are known to graze on kelp.

Without otters, sea urchin populations can grow unchecked and damage the kelp forest ecosystem. By keeping sea urchin populations under control, otters help maintain the balance between kelp and other organisms in the ecosystem.

The percentage of fish and invertebrates in the otter's diet can vary depending on their location and availability of prey. Otters are known to be opportunistic feeders and will consume a variety of prey depending on what is available. Studies have shown that otters can consume a range of invertebrates, including crabs, clams, and snails, as well as fish species such as rockfish and herring.

In general, when otters are present, there may be a lower percentage of sea urchins and a higher percentage of fish and invertebrates in the ecosystem.

Conversely, when otters are absent, the sea urchin population may grow unchecked, leading to a decline in kelp and potentially impacting other species that rely on the kelp forest ecosystem.
