Relate structure to function. c. Interdependence in nature is evident in symbiosis. Explain two symbiotic relationships that aid in nutrient uptake, using examples from angiosperms and/or vertebrates. (Both examples may be angiosperms, both may be vertebrates, or one may be from each group.)

Answers

Answer:

a. Angiosperm are plants (autotrophs) that use photosynthesis to produce their own food, while vertebrates are animals (heterotrophs) that obtain their food from other organisms. Vertebrates include fish, amphibians, reptiles, mammals and birds.

b. Adaptations in angiosperms include two reproductive structures 1- fruits (ovaries), whose main function is to disperse the seeds and 2- flowers that ensure pollination and protect the embryo sac during its formation.

c . Examples:

1- The mycorrhizal symbiosis between plant roots and symbiotic fungi plays a key role in nutrient uptake from the soil. Arbuscular mycorrhizal is a type of symbiosis where a fungus of the phylum Glomeromycota penetrates the cortical root cells of vascular plants to produce specialized structures named arbuscules.

2- Microflora in the vertebrate digestive tract. The microorganisms that live in the digestive tract of vertebrate species are beneficial for the absorption of nutrients.

b. pseudocoelom

Explanation:

A pseudocoelom is a false body cavity of some invertebrates which occupies the space localized between the mesoderm and the endoderm of the gut. This false cavity is found in nematodes.

Arthropods exhibit:

1- Bilateral symmetry because both opposite sides of the body are similar,

2- they are protostomes because the blastopore becomes the mouth during embryonic development,

3- they have true tissues because tissues are formed by groups of cells which share a common function, and finally,

4-arthropods are triploblastic because they are formed by three germ embryonic layers (endoderm, mesoderm and ectoderm).

Hemoglobin is the blood protein responsible for the transport of oxygen. Carbon monoxide disturbs oxygen transport by

Answers

Answer:

Answered below

Explanation:

Hemoglobin is found in the red blood cells and is responsible for the transportation of oxygen from the lungs to the various body cells.

Oxygen binds to hemoglobin because it has a high affinity for it. This aids its transportation. When it gets to the cells it unbinds and get transported into the cell for use in energy production.

Carbon monoxide is an odourless, dangerous gas which has more affinity for hemoglobin than oxygen. Therefore when carbon monoxide is inhaled, it quickly binds to hemoglobin, thereby displacing oxygen. It binds to hemoglobin for a longer period and due to this, the body does not get any oxygen and cells begin to die.

Symptoms of carbon monoxide poisoning include dizziness, headaches, fatigue and coma.

You observed many sand hill cranes on your walk. Two sand hill cranes flapped their wings and hopped up and down when you walked on the path near where their bright orange baby stood. You observed a(n) _______________.

Answers

Answer:

This question lacks options, the options are:

A) symbiosis

B) ecosystem

C) community

D) population

E) biosphere

The answer is D) Population

Explanation:

Living organisms in an ecosystem are usually found in numbers living together in a given area. This is termed POPULATION in ecology. A population refers to the group of living organisms that belongs to the same species living together in the same habitat and have the ability to interbreed i.e. mate and reproduce with one another.

This is the case in this question where many sandhill cranes (large flying birds) were observed in a particular area, which represented their habitat. Asides the group of sandhill cranes living together, they were also observed to be interbreeding. This was evident in the observation of two sandhill cranes hopping up and down around their bright orange baby. This shows that members of the population are capable of mating and reproducing fertile offsprings.

This observation completes what a POPULATION is all about, hence, a population was observed.

The mitochondrion, like the nucleus, has two or more membrane layers. How is the innermost of these layers different from that of the nucleus?

Answers

Answer:

The double membrane of the mitochondria is highly folded,and therefore wider when unfolded than that of the nucleus.This is an adaptive feature  to increase the surface area for reactions (electrochemical  gradient) by accommodating protons pumped into it by the proton motive force(PMF)  from the matrix to set up the electrochemical gradients needed to generate the energy needed by ATPase synthase enzymes for ATPs synthesis.

Required number of protons needed to be accommodated by the double membrane to generate enough energy for ATPase synthesis,therefore larger surface area is needed.

Explanation:

Mitochondria is the powerhouse of the cell, which is a membrane-bound organelle found in the eukaryotic cell. The inner layer of the mitochondria has cristae, which is absent in the outer layer.

Mitochondria is a membrane-bound organelle, which is composed of outer and inner layers.

The inner layer has cristae or folds, which increases the surface area for an electrochemical gradient.

The cristae are separated by cristae junctions, which are juxtaposed to the outer layer of the mitochondria.

The inner layer helps in electron transport and ATP synthesis. The membrane is surrounded by the mitochondrial matrix, which helps in the transportation of protein complexes during the citric acid cycle.

Therefore, the inner membrane of mitochondria has cristae whereas, the outer layer lacks the folds.

Answers

Answer:

The correct answer is "r-selected species".

Explanation:

The terms "k-selected" and "r-selected" species are used to describe two different type of evolutionary strategies. K-selected species are those who have few offspring that are well adapted to its environment and require a lot of resources to growth and survive. On the other hand, r-selected species have a large number of offspring, which not require living on stable conditions and can survive with few resources. The most invasive species are r-selected, since they reproduce very quickly and can adapt to survive to very different ecological conditions.

The uterine cycle describes the cyclic changes of thickening and degeneration that the endometrium goes through in a month. What is the order of events in one uterine cycle

Answers

Answer:

During the uterine month there are different phases through which the uterus passes, these phases are regulated by hormones and are responsible for producing the cycle necessary for fertilization.

Phase where menstruation occurs: This phase only happens if the woman was not fertilized and did not develop the diploid cell together with a sperm, since not being fertilized, all the uterine preparation that had been planned in the body for fertilization will be released as that we know "menstruation", in this phase estrogens and progesterone are low. The inner walls of the unfertilized uterus are released.

Follicular phase, in the follicular phase the ovaries prepare to release an egg and estrogen begins to rise. (From the first day of the period until ovulation)

Proliferative phase, in the proliferative phase, new vessels proliferate and the outermost layer of the uterus prepares itself for possible fertilization, is where spiral arterioles can begin to form again in the external cut of the myometrium.

Ovulation, here is where the mature ovum is called Graff's follicle, at this time estrogen reaches its peak and then descends.

Luteal phase, in the luteal phase the production of the luteal body is generated, at this stage progesterone takes center stage, and it is the range between ovulation and menstruation (if not fertilized)

Last phase, secret phase, in this phase there are two possible ends, if the woman is fertilized, the egg cell implants and begins the development of the embryo and if it is not fertilized, the entire external cut of the myometrium is prepared to be secreted.

Explanation:

A very important fact to clarify is that women are born with a quantity of ovules that at the end of this uterine cycle ceases to exist, this process is what we know as menopause.

That is to say that women have a quantity of ovules that will one day run out, and the body releases them from the menarche or the first menstruation, generating that in each released ovule a uterine cycle is completed, the day they end the woman will have reached menopause and would have no chance of being fertilized or completing the uterine cycle.

Answer:

The sequence is TCAA

Explanation:

Deoxyribonucleic acid (DNA) is a molecule composed of two complementary chains of nucleotides. The nucleotides are in turn composed of one nitrogenous base, one deoxyribose sugar, and one phosphate group. The four different types of nitrogen bases found in DNA are thymine (substituted by Uracil during RNA transcription), adenine, cytosine and guanine. These bases bind by complementary base pairing to form an antiparallel double-strand. The complementary base pairing rule states that thymine forms two hydrogen bonds with adenine, while cytosine forms three hydrogen bonds with guanine.

In the presence of saturating amounts of oxaloacetate, the activity of citrate synthase from pig heart tissue shows a sigmoid dependence on the concentration of acetyl‑CoA. When succinyl‑CoA is added, the curve shifts to the right and the sigmoid dependence is more pronounced.

Choose the statements that are reasonable explanations for the right-ward shift of the velocity curve caused by succinyl-CoA.

a. Succinyl-CoA competes with dissociation of CoA as a product of the reaction.
b. Succinyl-CoA binds covalently to the enzyme.
c. Succinyl-CoA binds at a regulatory site other than the active site.
d. Succinyl-CoA competes with acetyl-CoA for binding at the active site.
e. Succinyl-CoA competes with oxaloacetate for binding at the active site.

Answers

Answer:

c. Succinyl-CoA binds at a regulatory site other than the active site

Explanation:

The sigmoid saturation curve is a property of of allosteric enzymes which reflects the cooperaive interactions between the protein subunits in the enzymes.

Allosteric enzymes function through reversible, non-covalent binding of regulatory compounds called allosteric modulators.

Allosteric enzymes  have different binding site for the substrate and for their allosteric modulator.

In the citric acid cycle, succinyl-CoA serves as as allosteric inhibitor of citrate synthase which catalyses the production of citrate from oxaloacetate and acetyl-CoA.

From the given options:

a. Succinyl-CoA competes with dissociation of CoA as a product of the reaction is wrong because it has its own binding site as an allosteric modulator.

b. Succinyl-CoA binds covalently to the enzyme is wrong because allosteric enzymes functions through non-covalent interactions.

c. Succinyl-CoA binds at a regulatory site other than the active site is true because citrate synthase is an allosteric enzyme

d. Succinyl-CoA competes with acetyl-CoA for binding at the active site is wrong because acetyl-CoA binds to the active site while succinyl-Coa binds to the regulatory site.

e. Succinyl-CoA competes with oxaloacetate for binding at the active site is wrong because oxaloacetate binds to the active site while succinyl-Coa binds to the regulatory site.
