do thyroid hormones influence heart rate from influencing the heart itself, or the attached to it?

Answers

Answer 1

Answer:

An excess of thyroid hormones increases cardiac contractility and resting heart rate (see box below). Cardiac output may increase by 50-300 per cent as a result of the combined effect of increases in resting heart rate, contractility, ejection fraction and blood volume, with a concomitant decrease in SVR.

What is the name of the strategy that combines two plant proteins (grains and beans) to get all the essential amino acids

Answers

Answer:

Protein combining

Explanation:

The strategy involving the combination of two plant proteins to get all the essential amino acids is referred to as protein combining.

The practice of protein combining is common among vegans due to the general belief that a single plant-based protein does not contain all the necessary amino acids for the body. Thus, one would need to combine 2 plant-based proteins in order to get all the essential amino acids for adequate health.

Why do you think it is functionally important that the bones of the os coxae fuse together rather than remain independent bones

Answers

Answer:

Provides more strength.

Explanation:

It is functionally important that the bones of the os coxae fuse together rather than remain independent bones because the fusion of bones of the os coxae increases their strength and they can perform their function very well. If the fusion of bones of the os coxae did not occur and they remain independently so they can't bear the load of the body and so the function is also adversely affected.

Forms of inheritance that do not follow typical Mendelian patterns and that appear to be more influenced by the parent contributing the most cytoplasm to the embryo are grouped under the general heading of ________.

Answers

Answer:

Extrachromosomal or cytoplasmic inheritance

Explanation:

Extrachromosomal or cytoplasmic inheritance refers to hereditability transmission controlled by cytoplasmic genes.

This form of inheritance lays in genes that are out of the nucleus. Information for some characters is placed in organelles in the cytoplasm, such as mitochondria and chloroplasts. These organelles have a well-defined portion of the total cellular genome.

Although mitochondrial inheritance is mostly maternal, recent studies have demonstrated that it might also be paternal.

Sperm cells hardly carry mitochondria, so mitochondrial DNI is mostly inherited from the maternal side. If there exists any mutation in this DNI, the whole progeny of the mutated woman will be affected, as they will get the mother´s mitochondria carrying the mutation. On the contrary, if there is a man affected by a disease caused by a mutation in mitochondrial DNI, non of their descendants will get the disease.

Which of the following factors affecting population growth is density
independent?
A. Competition
B. Disease
C. Natural disaster
D. Predation

Answers

Hope this helps :)))

C. Natural disaster is a density-independent factor affecting population growth. Density-independent factors are those that affect the population irrespective of the population size or density.

How Natural disasters reduce population sizes?

Natural disasters such as floods, hurricanes, earthquakes, and wildfires can reduce population sizes regardless of how many individuals were present in the population before the disaster occurred. The other factors listed - competition, disease, and predation - are all density-dependent factors, which means that they become more significant as the population size or density increases.

Competition is an example of a density-dependent factor, as it increases as the population size increases. As more individuals compete for limited resources such as food, water, and shelter, the rate of population growth slows down.

Disease is another density-dependent factor, as it spreads more easily in crowded populations where individuals are in close contact with one another.

On the other hand, natural disasters such as floods, hurricanes, and wildfires are examples of density-independent factors. These events can affect a population regardless of its size, and they can cause significant decreases in population size.

Predation can be both a density-dependent and density-independent factor. In some cases, predation can increase as the population size increases, making it a density-dependent factor. However, predators can also reduce the population size through random hunting or selective hunting of weaker individuals, making it a density-independent factor.

Understanding the factors that affect population growth is important for predicting and managing population sizes in both natural and human-made ecosystems.

Given their size and complexity, biological molecules such as carbohydrates, proteins, lipids, and nucleic acids can also be referred to as ____________.

Answer:

This question lacks options, the options are;

A. Enlarged molecules

B. Macromolecules

C. Inorganic molecules

The answer is B

Explanation:

As mentioned in this question, carbohydrates, proteins, lipids, and nucleic acids are the basic biomolecules found in nature. They are all polymeric substances, hence, are made up of smaller units called monomers.

Asides from being biomolecules, these four molecules are also referred to as MACROMOLECULES based on their large size and complex nature. Macromolecules are molecules that are relatively large in size composing of an aggregate of monomer. Hence, these biomolecules are macromolecules.

After nervous stimulation stops, calcium ions returning to the sarcoplasmic reticulum prevent ACh in the synaptic cleft from continuing to stimulate contraction True False

Answers

Answer:

False.

Explanation:  

Neurotransmitter release occurs from the nervous terminal or varicosities in the neuronal axon. When an action potential reaches the nervous terminal, the neurotransmitter is released by exocytose. The molecule binds to its receptor in the postsynaptic neuron, triggering an answer. As long as the signal molecule is in the synaptic space, it keeps linking to its receptor and causing a postsynaptic response. To stop this process the neurotransmitter must be taken out from the synaptic space. There are two mechanisms by which the neurotransmitter can be eliminated:

Enzymatic degradation/deactivation: There are specific enzymes in the synaptic space, which are in charge of inactivating the neurotransmitter by breaking or degrading it. The enzyme acetylcholinesterase prevents ACh from continuing to stimulate contraction.

Reuptake: Receptors located in the presynaptic membrane can capture de molecule to store it back in new vesicles for posterior use. These transporters are active transport proteins that easily recognize the neurotransmitter.
