A researcher investigates an organism found on the ocean floor. The organism is asymmetrical. It lacks a body cavity, body tissues, organs, and a nervous system. The researcher finds that the organism can fully regenerate itself if parts of its body are broken off. Into which phylum should the researcher classify the organism?

Answers

Answer 1

The correct answer is option A, that is, Phylum Porifera.  

The species of Phylum Porifera are aquatic, that is, mostly marine. They exhibit cellular grade of the body, they are diploblastic animals with asymmetrical symmetry. They lack body cavity and exhibits a holozoic mode of nutrition with intracellular digestion.  

They lack circulatory and nervous system and possess the tendency to regenerate their parts of the body. The organisms in phylum Porifera exhibits both asexual and sexual mode of reproduction.

) Describe three benefits of CBT.​

Answers

Answer:

1. CBT can be completed in a relatively short period of time compared with other types of talking therapies.

2. Research has shown CBT can be as effective as medicine in treating many types of depression and other mental health disorders.

3. Skills you learn in CBT are useful, practical and helpful strategies that can be incorporated into everyday life to help you cope better with future stresses and difficulties.

Explanation:

Cognitive behavioural therapy (CBT) is a talking therapy that can help you manage your problems by changing the way you think and behave.

CBT cannot remove your problems, but can help you manage them in a more positive way. It encourages you to examine how your actions can affect how you think and feel.

Talking and changing your behaviour can change how you think (cognitive) and what you do (behaviour). This can make you feel better about life.

CBT can help you manage problems, such as anxiety and depression and make them less likely to have a negative impact on your life.

There is always a risk that bad feelings you associate with your problem will return, but with your CBT skills it should be easier for you to control them.

PLS HELP!!! What best describes the relationship between
P. caudatum and P. aurelia in Graph B?
Predation
Mutualism
Interspecific competition
Intraspecific competition

Answers

Answer:

Interspecific competition

Explanation:

Interspecific competition occurs when two different species occupy the same environment as they coexist and depend on the same limited resources for survival. As a result of these limited resources, there's competition between the different species with each species having their different levels of fitness. Their level of fitness determines how well they will complete with other species. This will also determine if they will go extinct or thrive in such environment where there's interspecific competition.

The graph given shows the growth of the relative population size of two different species grown together.

It shows that P. aurelia, with time, outcompetes P. coudatum.

This graph clearly suggest that interspecific competition has occurred. Both species are competing for the same limited resources.

P. aurelia has a greater fitness which enables it to outcompete the other species sharing the same environment with it.

Interspecific competition beats describes the relationship between the two species in graph B.

B. Blood pumped from the heart first enters veins that the narrow to form venules that deliver blood to arteries of the organ.
C. Blood pumped from the heart first enters arterioles that the merge to form artenes that liver blood to the organ.
D. Blood pumped from the heart first enters artenes that the narrow to form veins that deliver blood to the organ.

Answers

Answer:

A.

Explanation:

Human heart is an organ that is responsible for the circulation of blood throughout the body and works in a systematic pathway.

The human heart recieves blood from two large veins, the superior and inferior venae cavae and enters through different chambers in the heart that is first at right atrium to right ventricle, from right ventricle to left atrium, then from  left atrium pumped into the left ventricle.

The blood first enters into arteries and than move to narrorwer to arterioles that deliver blood to capillaries of the organ where the oxygen and nutrients from blood are supplied to body cells for metabolism and the deoxygenated blood enters into veins.

Hence, the correct option is "A".

The Vmax of the isoform of glycogen phosphorylase expressed in muscles is significantly larger than the isoform of the enzyme expressed in the liver enzyme. Explain the functional significance of this observation.

Answers

Answer and Explanation: In enzyme kinetics, one constant describing enzyme activity is Maximal Velocity (Vmax). It indicates how fast an enzyme can catalyze the reaction. It is dependent on substrate concentration.

As the muscle is an organ which needs a great amount of energy, the enzyme glycogen phosphorilase is very active on the organ, compared to the liver, where glicose is stored. So, the Vmax of glycogen phosphorylase expressed in muscle is faster than when expressed in the liver, means the enzyme in muscle has a bigger concentration of substrate and therefore will reach Vmax faster, i.e. will be significantly larger.

What is an example of how organic molecules play a role in the structure and function of different cell types

Answers

Answer:

For example, the sugars can be linked to form polysaccharides such as starch and glycogen, the amino acids can be linked to form proteins, the nucleotides can be linked to form the DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) of chromosomes, and the fatty acids can be linked to form the lipids of all cell

Explanation:

Organic molecules play a significant role in the structure and function of different cell types. For example, nucleic acid looks after the construction of genetic material among living organisms.

What are organic molecules?

Organic molecules may be defined as all sorts of those molecules that primarily consist of carbon and hydrogen. It also includes other elements like oxygen, nitrogen, phosphorus, etc. Organic molecules must possess carbon atoms covalently bonded to hydrogen atoms (C-H bonds).

Among organic molecules, carbohydrates are the energy-deriving components that all cells require in order to perform their own cellular and metabolic activity.

Proteins are required for the structural arrangement and specific function of each cell type. It also functions as a hormone or enzyme. Lipids also store the energy needed for the body.

Therefore, organic molecules play a significant role in the structure and function of different cell types.

Which of the following is NOT a mechanism used to temporally regulate the activity of maturation-promoting factor (MPF)?
A. the presence of mitotic cyclin
B. specific dephosphorylation
C. glycosylation
D. specific phosphorylation

Answers

Answer:

C. glycosylation

Explanation:

The maturation-promoting factor (MPF) is a cell cycle checkpoint that stimulates the passage from G2 (prophase) to M phase (metaphase). MPF also determines that DNA replication during the S (synthesis) phase did not produce any mutations. MPF is inactivated by kinase phosphorylation and activated by specific phosphatases capable of dephosphorylating this protein. On the other hand, glycosylation is a posttranslational modification where a carbohydrate (i.e., a glycan) is added to a functional group of another molecule. Many proteins undergo glycosylation, thereby playing a critical role in regulating protein function.

Women have a tendency to retain water during part of the menstrual cycle because estrogen mimics the action of what

Answers

Answer:

This question lacks options, options are:

A) ADH

B) aldosterone

C) atrial natriuretic hormone

D) oxytocin

E) prolactin

The correct answer is B.

Women have a tendency to retain water during part of the menstrual cycle because estrogen mimics the action of aldosterone.

Explanation:

The female sex hormones produced by the ovary (estrogens and progesterone) are substances that, through the blood, will carry messages to all the organs of the female genital system (uterus, tubes and ovaries) to achieve their correct function. Aldosterone concentration normally increases at the time of ovulation and remains elevated during the luteal phase of the menstrual cycle. Women present during the premenstrual phase, compared to the luteal and follicular phases, an increase in body weight, due to an increase in fluid retention, this because the menstrual cycle modulates the renin-angiotensin-aldosterone system. High levels of estrogen and progesterone in the mid-luteal phase are associated with a greater increase in adrenal and renal hormones and retention of more volume.
