Answer:

The correct answer is what is the effect of exercise on heart rate in horses?

Explanation:

An individual who possesses the knowledge in the field of biology is known as a biologist. It is a multidisciplinary subject that comprises various branches like zoology, botany, and others. Of the mentioned questions, the effect of exercise on the heart rate of the horses comes under zoology category. In this field, one studies about the influence of various constituents found in the surrounding on the health of animals.

When performing a wall sit or a squat (repeated motion with the squat), what major muscle groups are being used

Katen [24]

The major muscles involved while performing a wall sit or squat are the quadriceps muscles.

Explanation:

Exercises like wall sit or squat are an isometric exercises which works the entire group of lower body muscles.

Isometric exercises are endurance building exercises which improves the muscle endurance by holding it in a position for longer time. These exercises does not involve any big bodily movements but works by tensing the muscles.

Both these exercises primarily involve the front thigh muscles or the quadriceps. Squats and wall sits help to tone and shape the quads and other muscles involved. The angle of the body should be maintained at right angle to reduce the pressure on these muscles.

Other muscles which are involved in these exercises are the hamstrings, core, lower back muscles etc.

What is an advantage of using nuclear power?

My name is Ann [436]

Large nameplate capacity per plant, typically around 1 GW.
Typically 90% capacity factor, maximizing output from the nameplate capacity.
Small fuel transportation volumes as the fissionable material just isn't that big or heavy compared to equivalent fossil fuel BTU sources.
Low CO2 per MWH on a full life cycle basis. ~12 grams which is only slightly more than wind / solar.
This is a reason nuclear is a much better source for one of the major pressing problems of today than fossil fuels: global warming.No particulate matter pollution.No sulfur dioxide or other chemical pollution.Low fatalities per TWH.
Nuclear is higher than renewables according to current statistics, but much, much lower than fossil fuel generation.

Nuclear power generates lots of clean, stable energy.

Granite is a common type of rock found in Yosemite National Park. Limestone is a common type of rock found in Kentucky.

Elena-2011 [213]

Answer:

You should visit Kentucky.

Explanation:

Limestone is a sedimentary rock formed from the calcareous remains of dead creatures. Limestone is mostly made of shells and other remains of organisms that have collected over time. These are good conditions for fossilization. Granite, however, is an igneous rock formed from solidification of magma in the Earth's crust. High temperatures and extreme conditions make fossilization unlikely.

Classify the following characteristics depending on if they describe events occurring in mitosis, meiosis I, or meiosis II.

Temka [501]

Answer:

Mitosis events are:

Results in 2 genetically identical

diploid nuclei

A diploid number of sister

chromatids align at the spindle

equator during metaphase

Meiosis I events are:

Results in 2 genetically diverse

haploid nuclei

Homologous chromosomes align

at the spindle equator during

metaphase

Homologous chromosomes pair

up during prophase

Crossing-over occurs during

synapsis

Meiosis II events are:

Results in 4 genetically diverse

haploid nuclei

A haploid number of homologous

chromosomes align at the spindle

equator during metaphase

Explanation:

Mitosis is a type of cell division which produces two daughter cells that are genetically identical to the parent cell. In mitosis, the chromosome number of the parent cell is maintained in the daughter cells i.e. a diploid cell (2n) will undergo mitosis to produce two diploid (2n) daughter cells. During mitotic division, sister chromatids (replicated chromosomes) are involved in the division stages. i.e. diploid sister chromatids align at the equator of the cell during Metaphase and also sister chromatids are separated or pulled apart to opposite poles during Anaphase.

Meiosis, on the other hand, is a kind of cell division that results in daughter cells with a reduced number of chromosome (by half). Since the chromosome number is reduced, meiosis occurs in a two step division process viz: Meiosis I and II.

Meiosis I produces two genetically different daughter cells. The daughter cells have a reduced number of chromosomes i.e. from diploid (2n) to haploid (n). Meiosis I involves homologous chromosomes (similar but non-identical chromosomes received from each parent) which pair up to form a TETRAD structure in the Prophase stage. This structure allows for an exchange of chromosomal segment between non-sister chromatids of homologous chromosomes, a process called CROSSING-OVER. Crossing-over is what makes the daughter cells genetically different from the parent cell. Homologous chromosomes also aligns at the equator of the cell during Metaphase and later separates during Anaphase.

Meiosis II divides the two daughter cells produced in meiosis I into four genetically different daughter cells. Since the chromosome number has been reduced from diploid (2n) to haploid (n) in meiosis I when homologous chromosomes separate, haploid sister chromatids are involved in the stages of meiosis II i.e. haploid sister chromatids align at the equator of the cell during Metaphase and eventually becomes pulled apart during Anaphase.
