The main difference between species and genus is the taxonomic rankings that are used for biological classifications of organisms. Genus belongs to a ranking lower than family and above species, whereas species are organisms with similar characteristics that come below the Genus classification ranking.
Part of a forest area was cleared to build a road. What’s one possible consequence of this clearing?
A.
The rate of the growth of trees will increase.
B.
The population of herbivorous animals will increase.
C.
Animals will migrate to other places because they have less food and shelter.
D.
The frequency of forest fires will increase.
Answer:
Option C
Explanation:
Animals will migrate to other places because they have less food and shelter. Since the forest have been cleared, their habitat (where they lived) is no more and they have to move to another place in order to survive because there would be no more food for them here.
Answer:
The answer is option C.
Animals will migrate to other places because they have less food and shelter.

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
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.
superficial layer of the endometrium is shed
basal layer of endometrium grows, forms gland and blood vessels
enriched endometrial blood supply
endometrial glands secrete nutrients into uterus
Hemoglobin is the blood protein responsible for the transport of oxygen. Carbon monoxide disturbs oxygen transport by
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.
Angiosperms (flowering plants) and vertebrates obtain nutrients from their environment in different ways. a. Discuss the type of nutrition and the nutritional requirements of angiosperms and vertebrates. b. Describe 2 structural adaptations in angiosperms for obtaining nutrients from the environment. 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.)
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. For example, in humans, Saccharomyces boulardii has shown to have a probiotic effect by increasing intestinal homeostasis, thereby enhancing nutrient uptake.
What is a cell and what are the function of each
Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.

Answer:
the misinformation effect
Explanation:
In psychology, misinformation effect occurs when false memories are formed as a result of the misleading information that was provided after the original event has taken place. This effect was studied by a psychologist named Elizabeth Loftus.
Elizabeth Loftus in her series of experiments discovered that false memories about an event can be induced by suggesting or giving wrong information about it. Hence, the involved persons remember a wrong information about the experienced event based on what they were led to remember via wrong information.
This is the case Felice, who was fed with a wrong information about the scar on her arm. This information make her have a false memory of the event i.e dog bite instead of a broken glass
1. One important feature of DNA is that it can be accurately copied and inherited from one generation to the next. Imagine if DNA was NOT accurately replicated. What errors could occur and how would they affect the offspring in the next generation
Answer:
Explanation:
If DNA is not accurately replicated it can lead to mutation. Mutation is a genetic disorder that occur when a change occur and affect the genome of an organism. It can be result in frameshift mutation shifting nucleotide arrangement.
When DNA is not accurately replicated, it could lead to formation of an entirely new protein different from the original which has a different function this could lead to a form of disorder in the offspring. The effect of this disorder depends on it severity.

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.
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.

2. If a nucleus has 8 chromosomes, how many chromosomes will be present after Telophase I? 3. What advantage does crossing-over have in reproduction? 6. Compare and contrast spermatogenesis and oogenesis (where do they occur, how many gametes are formed, when do they develop, etc):
Answer:
Telophase I: 8 chromosomes composed of two sister chromatids
Crossing over refers to the mechanism of recombination, this process being characterized in that increases the genetic variation
Spermatogenesis refers to the mechanism of formation of male gametes (sperms), while oogenesis is the process of formation of female gametes (oocytes)
Explanation:
Telophase I is the final step in meiosis I. During telophase I, the nuclear membrane is formed around the decondensed set of chromosomes and the nucleoli reappear.
Spermatogenesis refers to the process by which haploid male germ cells (sperms) are generated within the seminiferous tubules in the testis, while oogenesis refers to the process of differentiation of the female egg cells (ova or oocytes) in the ovaries. Spermatogenesis is known to produce small and motile spermatic cells, while oogenesis is known to produce bigger non-motile oocytes.
