Answer:
A superficial injury to the spinocerebellar tracts results in loss of coordinated movements of the trunk and lower extremities and presents with an abnormal clinical sign termed Ataxia.
Explanation:
Lesions of spinocerebellar tracts are ipsilateral. hope this helps you :)
The effects of a superficial lesion of the spinocerebellar tracts would be:
1) Muscle incoordination
2) Muscle tone disorders
The anterior spinocerebellar tract transmits proprioceptive information from the upper and lower limb tendon and joint receptor neuromuscular spindles.
The posterior spinocerebellar tract carries proprioceptive information from the trunk and lower limb.
All this information is integrated by the cerebellar cortex to later coordinate movements and maintain body posture.
A superficial injury to the spinocerebellar tracts would directly affect muscle tone (a state of permanent semi-contraction of the muscles), and an inability to coordinate movements.

Hemophilia is a sex-linked recessive trait in humans. If a father and a son are both hemophiliacs, but the mother is normal, her genotype must be____. (Note: the H's are superscripts.) * XhXh XHXh XHXH XhY
Answer: XHXh (Note: the H's are superscripts.)
Explanation:
Hemophilia is a sex-linked recessive trait which means that the males having one altered copy of the gene is enough to cause the medical condition( as they have only one X chromosomes and females have two)
In this case the genotype of father and son is such that they are affected by hemophilia.The son has mother's X chromosome and father's Y chromosome.
XhY is the genotype of father and son. As mother would be heterozygous because she is not affected, her genotype will be XHXh.
Round seeds and yellow seed color are dominant to wrinkled seeds and green seed color. What is the probability of having offspring that have wrinkled seeds and yellow seed color for the cross RRYY ´ RrYy?
Answer:
The probability of a cross between RRYY x RrYy to generate a yellow and wrinkled seed offspring is 0%.Explanation:
Circular and yellow seeds are overwhelming and wrinkled and green seeds are passive. It is vital to keep in mind that resective characteristics are as it were displayed when the sibling has two passive alleles for those characteristic, in the event that the descendant includes a latent allele and a overwhelming allele, the characteristic that will be presented is the overwhelming one. For this reason, able to say that a cross between RRYY x RrYy plants, would not create any descendant with wrinkled and yellow seeds. Typically since, the descendant of a crossing, must show an allele of each parent. One parent as it were has overwhelming alleles (RRYY), so able to say that all descendant will get 1 overwhelming allele for color and a overwhelming allele for seed surface, anticipating the sibling from communicating latent characteristics.

The cell cycle describes the processes that take place as a cell Your answer: A.forms new cells. B.absorbs nutrients. C.makes proteins.
Answer:
Choice A
Explanation: This is because the main purpose of the cell cycle is to create new cells for the organism via mitosis or meiosis.
The cell cycle illustrates the procedures, which occurs as a cell produces new cells.
What is cell cycle?It refers to a series of events, which occurs in a cell as it grows and differentiates.
A cell devotes majority of its time in the phase known as interphase, and during this time it develops, divides its chromosomes, and prepares for the division.
After that the cell leaves interphase, and goes through the process of mitosis, and completes the process of division.
It can be said that the prime task of cell division is to produce novel cells.
Thus, the correct answer is option A, that is, forms new cells.

Which phylum is a group of miscellaneous fungi that don’t fit into the other three categories? Zygomycotes Deuteromycotes Ascomycotes Basidiomycotes
Answer:
Deuteromycotes
Explanation:
Kingdom Fungi consist of eukaryotic organisms grouped into 3 phyla, with one group that doesn't fit into any of the grouped three. Each group of fungi were classified into phylum based on their reproductive life cycle. The three phyla are Zygomycotes, Ascomycotes, Basidiomycotes.
Zygomycotes produce their spores by meiosis in a structure called Zygosporangium. Ascomycotes produce their spores via meiosis in ascus (sac-like). Basidiomycotes produce their own spores via meiosis in club-like basidium.
However, a fourth group exists that has no known sexual reproductive structure (meiospores), instead it is known to reproduce asexually via mitospores. This group is called DEUTEROMYCOTES or commonly known as FUNGI IMPERFECTI. It is a group of miscellaneous fungi that doesn't fit into the classification basis of the other three phyla.

Which of the following is used as cellular support for cells and unicellular organisms?
A) chloroplasts
B) lysosomes
C) endoplasmic reticulum
D) microtubules
Answer:
D. Microtubules
Explanation:
Microtubules are made of proteins (largely) that make up a cell's cytoskeleton, which provides the internal support framework for the cell.
The correct option is, (D) microtubules.
The cytoskeleton of a cell, which provides the internal support structure for the cell, is primarily made up of proteins, which are the building blocks of microtubules.What is the function of the endoplasmic reticulum?In general, the endoplasmic reticulum's job is to make proteins so that the remainder of the cell can operate. It can be smooth or rough. Ribosomes, which are tiny, elongated organelles with a round shape, are found on the rough endoplasmic reticulum and are responsible for producing those proteins.Which of following organelles help with cellular movement?The cytoskeleton not only performs this structural function, but it also controls how cells move. These involve not just the internal movement of organelles and other structures (such mitotic chromosomes) through the cytoplasm, but also the motions of whole cells.Which organelle provides energy for the cell?Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).Hence, microtubules is used as cellular support for cells and unicellular organisms.

What are some of the consequences of acid rain? Thanku
The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes. The more acid that is introduced to the ecosystem, the more aluminum is released, die of biodiversity in environment and other organism that supports decomposition of material
Ramu wants to practice crop rotation in his field. Suggest a Rabi crop and a Kharif crop, which will replenish his field with nitrogen. Which crop replenishes nitrogen and why?
Answer:
Explanation:
is a practice that involves the growing of different type of crop on the same piece of land. It is often practices by subsistence farming where the land space is not to big to accommodate all the crops to be grown separately.
Nitrogen are been replenished into the soil by leguminous crops. This is because they have root nodules which contains Nitrogen and it help fixes it back into the soil with the help of bacteria such as Azotobacter, nitrogen fixing bacteria. This bacteria acts on the nodules to help break down the Nitrogen into a form that can be useful by plants.
Example of kharif Crop is pea which are leguminous and can fix nitrogen back into the soil, maize, rice
Rabi example is wheat and barley.

Explanation:
Answer:
Secondary succession
Explanation:
Succession may be defined as the change in the biological species community with time. Primary succession and secondary succession are two main types of succession.
Secondary succession is the succession that occurs most often in nature because this succession occurs when the climax community is disturbed by the natural and man made disturbances. The secondary succession has almost every thing to start the new succession again in the destroyed land.\

Which statement accurately describes tectonic plate movement? Tectonic plate movement can be prevented with planning. Tectonic plate movement does not cause environmental change. Tectonic plate movement does not affect organisms. Tectonic plate movement is a long-term environmental change.
Answer:
The correct answer is Tectonic plate movement is a long-term environmental change.
Explanation:
When tectonic plates in the earth started to move, this process helped the planet to evolve and to shape the continents as exist today.
Different investigation teams have discovered that plates move approximately 2.5 centimeters per year. This movement is the key to the evolution of life and the development of the planet. This slow process involves mountain formation, rocks exposure, and chemical reactions that could stabilize the temperature on the earth´s surface for millions of years. And this stable weather is essential for the evolution of life. Plates movement carries carbon inside and outside of the planet, regulating the amount of carbon dioxide in the atmosphere (greenhouse effect). In this way, it can regulate the temperature. This regulation influence in precipitations, chemical reactions that involve carbon release and minerals such as calcium, the water flow, volcanic eruptions, among other events. Plates tectonic is also responsible for life, as weathering and mineralization of the rocks release elements and nutrients that are necessary for the life of different organisms.
So, up to this point, we can say that tectonic plates movement can not be prevented with planning, it does cause environmental change by regulating temperature, and hence it affects organisms.
There are short term effects and long term effects provoked by tectonic plates movement. Earthquakes are examples of short term effects, while mountain formation, ocean formation and, clime regulation are examples of long term changes.
Plates tectonic movement is a very slow process, that might last many years. The Andes formation, for example, started approximately 200 years ago, and these mountains are still rising. The subduction process has not finished as the plates are still moving.
