Why do parasites not require complex nervous or muscular tissue?

Porque los parásitos no requieren tejido nervioso o muscular complejo?

Answers

Answer 1

Answer:

Hey mate.....

Explanation:

This is ur answer.....

Poorly developed nervous and muscular systems – because parasites live inside their hosts, they don't need eyes, ears or a keen sense of smell to detect potential predators nor a brain to facilitate escape. They have little need for a muscular system because they have no place to go.

Answer: A)consistency

Explanation:

Genes which are expressed all the time.

Answers

Genes that are expressed all the time are dominant ones. They can also be seen all the time if it is a genotype(ie. eye color, hair color, etc.)

Which of the following sentences state a significant conclusion that Gregor Mendel drew from his experiments with pea plants? Traits are inherited in discrete units and are not the result of "blending." Genes are composed of DNA. Recessive genes occur more frequently in the F1 generation than do dominant ones. There is considerable genetic variation in garden peas.

Answers

Mendel concluded that the alternative forms of each trait are coded by discrete factors, which were called alleles that combine in pairs to express the trait. Traits are inherited in discrete units and are not the result of "blending."

------------------------

After making many crosses that involved different traits -such as plant height, or flower colors-, Mendel observed that, per trait, the F1 only expressed one of the alternative forms, while de other one disappeared.

Mendel named dominant the expressed variant.

Mendel then let these new plants auto pollinate and observed the results in the second generation, F2.

He saw that the variants that had previously disappeared among the F1, reappeared again. Both alternatives for each trait were present in the F2.

Mendel named recessive the second alternative variant.

Mendel explained his results by arguing that discrete factors were responsible for these phenotypes.

These factors should have been present in the F1 in pairs.

One of them came from one parental plant, and the other factor came from the other plant.

These factors separated again during sex cells formation, producing two types of gametes, each with only one factor.

Mendel conclusion about his experiments was that per trait -flower color of plant length-, each plant had a pair of factors -which he named alleles-, and that each factor coded for one of the alternative forms of the traits -white or purple, tall or short-.

He thought that alleles separate -segregate- during the process of gamete formation.

The First Mendel's Law is the first conclusion he took about his experiments and is known as the segregation principle.

What happens to the states of matter when the temperature changes

Answers

    They may either release heat or gain heat. With a temperature increase, the kinetic energy increases and the state of matter will increase (example, ice to water aka solid to liquid)

    If the temperature decreases, then the kinetic energy decreases and the state of matter will decrease (example, water vapor to water aka gas to liquid)

Receptors for neurotransmitters are of primary functional importance in assuring one-way synaptic transmission because they are mostly found on the Axonal membrane.

What are Neurotransmitters?

Neurotransmitters may be defined as the type of chemical substances that are correspondingly liberated at the end of a nerve fiber by the arrival of a nerve impulse and, by diffusing across the synapse or junction. They are released in the location known as the synaptic cleft.

The receptors of these neurotransmitters are present in the plasma membrane of postsynaptic cells which selectively bind the transmitter. They are integral membrane glycoproteins with multiple transmembrane segments.

Some examples of neurotransmitters may include serotonin, GABA, dopamine, acetylcholine, etc.

You are infected with a pathogen; it is your first exposure to this pathogen. The first antibody types that will eventually appear in your blood to help fight this infection will be:

Answers

If it is the first time that this pathogen comes into contact with the immune system, IgM antibodies are produced, which are the first type of antibodies produced against a certain microorganism.

Immunoglobulins are molecules that intervene in defense processes against microorganisms and infections.

Each type of immunoglobulin is specific against a certain antigen, this is what allows an immunological memory to exist, which is obtained when coming into contact for the first time with a certain microorganism.

IgM is the first immunoglobulin synthesized by the neonate by itself, and it is also the first to appear during the primary response, which lasts an average of three weeks and then disappears.

In general, the production of IgM antibodies precedes that of IgG, the concentration of antibodies can be high, plateau for a few days and then decrease rapidly.

Therefore, we can conclude that when the immune system first comes into contact with an antigen, a primary response occurs; mediated by IgM antibodies.

Crossing over is a process that occurs during formation of gametes. How does crossing over lead to genetic variation in offspring?

Answers

Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells, and different chromosomes segregate independently of each other.
