Under normal conditions the sympathetic division is usually active in the body resting heart rates are influenced by nor epinephrine the parasympathetic system keeps heart rate lower than the heart would beat on its own. all of the above are true

Answers

Answer:

the parasympathetic system keeps heart rate lower than the heart would beat on its own.  

Explanation:

The parasympathetic nervous system (PNS) is one division of the autonomic nervous system. The vagus (parasympathetic) nerves that innervate the heart release acetylcholine in order to slow the heart rate by decreasing the slope of the pacemaker potential. Acetylcholine activates a type of G-coupled protein receptor known as muscarinic receptors, allowing for a parasympathetic reaction in the cardiovascular system (where these receptors are expressed), and thereby decreasing cardiac output by inhibiting heart rate. During rest, PNS predominates and controls the heart rate at a resting rate of 65-80 beats/minute (bpm), if parasympathetic nerves to the heart are cut, then the heart beats at its own rate of about 100 bpm.

Evalute paper bags versus poly bags on the following parameters strength, cost, reusability impact on environment ​

Answers

Answer:

Poly bags are more stronger than paper bags.

Explanation:

Poly bags are more stronger than paper bags due to the use of materials in it while on the other hand, cost of production on the poly bags is less than paper bags. Poly bags can't be reuse whereas the paper bags can be used. The poly bags causes more pollution in the environment due to its non-degradable nature as compared to paper bags that degrades easily and has a good impact on environment.

As you read in this chapter, fungi have long formed symbiotic associations with plants and with algae. How may these two types of associations lead to emergent properties in biological communities

Answers

Answer:

Fungi show symbiotic association with algae and plants. With plants, they thrive as endophytes in a form of the symbiotic association. This symbiotic association results in the emergence of novel characteristics in the world of biology.  

The lichens function as a tool in finding the quality of air, as they grow in the environment containing good air quality. The tolerance towards heat is another characteristic. Some of the endophytes are witnessed in the plants, which grow in very hot conditions.  

At such conditions, no fungi or plant can thrive, however, in the symbiotic association, they possess the tendency to thrive. If one tries to separate them, it results in the death of both.

Given the enormous heterogeneity of antigen receptors expressed on the populations of naive B and T lymphocytes, the adaptive immune response relies on a process whereby the rare lymphocyte that binds to the antigen is first induced to proliferate, before it can perform its effector function. For B cells, there is a clever mechanism that ensures that the specificity of the antibody secreted by the plasma cell will recognize the same pathogen that initially stimulated the B cell antigen receptor and induced B cell proliferation. This mechanism is:

Answers

Answer:

The naïve B cell expresses a membrane-bound form of the antibody as a receptor and secretes that same antibody when it differentiates into a plasma cell.

Explanation:

Naive B cell is a type of B cell that has still not been exposed to the antigen. The B cell receptors (BCRs) are transmembrane proteins composed of 1-a surface immunoglobulin molecule capable of recognizing the antigen, and 2-two transmembrane subunits that transduce the signal. When a B cell binds to antigen with its BCR, the B cell will proliferate and differentiate into a plasma cell. This plasma cell then releases antibodies, which are soluble forms of the BCR where the transmembrane domain that anchors the antibody protein to the membrane of the B cell is eliminated.

In April 1990, the El Paso County (Colorado) Health Department recognized an outbreak of drug-resistant gonorrhea in Colorado Springs. 56 cases of penicillin- resistant Neisseria gonorrheae occurred from December 1989 through March 1991. To gather information about the outbreak, 410 persons related through a densely connected set of social or sexual associations were interviewed. What can public health workers tell individuals in this network to stop the spread of Gonorrhea in this population?
a) Preventive treatment with penicillin will prevent Gonorrhea infection in individuals not already infected.
b) Only individuals with symptoms should seek medical screening since all cases of Gonorrhea are associated with symptoms.
c) Condoms will not prevent the spread of Gonorrhea. Gonorrhea can spread from an infected mother to a fetus.
d) Gonorrhea is more prevalent in individuals 24 years and older.

Answers

Answer:

c) Condoms will not prevent the spread of Gonorrhea. Gonorrhea can spread from an infected mother to a fetus.

Explanation:

To prevent the spread of infection, it is important that healthcare professionals inform people about ways to protect themselves against infection. In addition, it is important that health professionals inform the dangers that this infection can cause, such as symptoms and rapid transmission, which can even happen from mother to fetus. On how to protect themselves, health professionals can say that the use of condoms is the most efficient form of protection.

Answers

Answer:

Dark colour.

Explanation:

Dark fur color seems to have the greatest selective advantage because of their hard physical body which occurs due to extreme environmental conditions. The dark colour of mice occurs due to the high intensity of sunlight which increases melanin in their skin. These dark colour mice pass through a very hard and extreme environmental conditions so that's why Dark fur color seems to have the greatest selective advantage.

6.Two apparently normal parents have a daughter who suffers from agammaglobulinemia (AGG), an inherited defect of the immune system. Use a Punnett square to show how two normal parents could have a child afflicted with an inherited disease. What are the parents' genotypes

Answers

Answer:

See the answer below

Explanation:

For two normal parents to have produced a daughter who suffers from AGG, it means the disorder is an autosomal recessive trait. In order words, it means the parents are both carrying the allele for the disorder in recessive form.

Let us assume that the allele for the disorder is represented by b, meaning that the alternate form would be B. Both parents will have the genotype Bb and will both appear normal.

      Bb    x    Bb

    BB   Bb   Bb   bb

The affected child would be the one with bb genotype while the remaining children would appear normal. See the attached image for the Punnet's square analysis of the cross.

The genotypes of the parent would be heterozygous.

Biological organization extends beyond the organism. Which group of terms would be included beyond organism in the same list

Answers

Answer:

This question lacks options, the options are:

A. populations, communities, and ecosystems

B. DNA, RNA, and protein

C. Cells, tissues, and organs

The answer is A

Explanation:

The biological level of organization shows the organized build up of life from cellular level to organismal level. However, this organization goes beyond the organismal level. Individual species of organisms can assemble to form a POPULATION.

Likewise, populations of different species can coexist to form a COMMUNITY. The community of organisms can interact with their abiotic environment to form an ECOSYSTEM.

Therefore, the level of biological organization extends as follows:

populations → communities → ecosystems

Put the following steps of Meiosis in the correct order:

I. The cell divides into 2 daughter cells
II. Homologous chromosomes pair up in the center of the cell
III. Spindle fibers separate homologous chromosomes
IV. Chromosomes become shorter and thicker
A. I, II, III, IV
B. IV, III, II, I
C. II, III, I, IV
D. IV, II, III, I

Answers

C.
Because first thing that happens in meiosis is the homologous pairs come in the center of the cell. Without that happening first, the cell can’t divide into 2 daughter cells, so it is NOT option A.
Chromosomes will become shorter and thicker at the end so the only option that remains is C.
Homologous chromosomes pair up in the center of the cell.Spindle fibers separate homologous chromosomes.The cell divides into 2 daughter cells.Chromosomes become shorter and thicker.

What is Meiosis

Meiosis  (listen); from Ancient Greek'lessening', since it is a reductional division) is a special type of cell division of germ cells in reproducing organisms that produce the gametes, such as sperm or egg cells. It involves two rounds of division that ultimately result in four cells with only one copy of each chromosome (haploid). Additionally, before the division, genetic material from the paternal and maternal copies of each chromosome is crossed over, creating new combinations of code on each chromosome. Later on, during fertilization, the haploid cells produced by meiosis between a male and female will fuse to create a cell with two copies of each chromosome again, the zygote.

Errors in meiosis resulting in aneuploidy (an abnormal number of chromosomes) are the leading known cause of miscarriage and the most frequent genetic cause of developmental disabilities.

Muscle weakness is associated with Vit A/ Vit E/ Vit K/ Protein deficiency

Answers

Sorry if it wrong but I think it is Nerves, or blood vessels

Answer:

Low vitamin E levels may result in Muscle weakness: for the central nervous system, vitamin E is vital. It is one of the major antioxidants in the body and a shortage causes oxidative stress that can lead to weakening in muscles.

Explanation:

The body needs to work with vitamin E and become a necessary vitamin. It is fat-soluble, thus it has to be effectively absorbed in fat from the food. Before being released to the bloodstream for usage, vitamin E is mostly kept in the liver.

The deficiency is unusual and usually caused by an understatement. There are also modest levels of preterm newborns.

Eight kinds of vitamins exist. A blood test allows a physician to know how much a person has of an alpha-tocopherol form. Use this information to establish if the total vitamin E level of a person is present.

A standard level is typically between 5.5 and 17 milligrams (mg/L) per litre. For premature infants and youngsters under 17 years, the typical range may be different. The Normal scope may also be somewhat different amongst laboratories.

If an adult has less than 4 mg/L of vitamin E in his or her blood, supplementation is usually necessary.
