Answer:

Oxygen is important because it makes aerobic respiration possible by accepting electrons from the transport chain in the mitochondria. Sometimes oxygen is unavailable in some of your muscle cells (typically during heavy exercise); at times like these, the muscle cells will temporarily revert to lactic acid fermentation, which yields far less energy.

Explanation:

Answer:

Well oxygen is important for cellular respiration when it comes to humans and some other animals but for some other organisms and cells they don't require oxygen.

Explanation: Why we would say oxygen is important for the cellular respiration of humans is because if you take it away this can destroy the whole process of cellular respiration which can harm the humans.  Metabolic poisons or Rat poisons work in a similar way by disrupting process done by enzymes in cellular respiration so just like that taking oxygen will disrupt cellular respiration in the human harming them or even causing death as parts of the cell such as the mitochondria use it in fact one of the parts of the cycle for making ATP for some animals requires oxygen such as the Krebs cycle.

Answer:

animals

mammals

vertebrate

Explanation:

cows have a backbone so they are a vertebrate

cows have hair so they are mammals

and the are animals just like every other living thing

Three terms used to describe organisms such as cows are:

An organism, especially a cow, is a living thing. An organism is a singular living being that exhibits characteristics of life, such as the ability to develop, reproduce, respond to stimuli, and preserve homeostasis. Mammalia, a class of multicellular organisms including cows, forms the animal kingdom. Cows are complex biological entities with specialized sensory and digestive systems that enable them to live and thrive in their environment.

The following three terms are used to describe cow-like creatures:

Cows are mammals, which are warm-blooded animals with hair or fur and the ability to feed their young with milk.

Herbivores: Cows are herbivores, which means they only eat plants and no animal products like meat or dairy.

Cows are included in the class of herbivorous mammals known as ruminants, which have a four-chambered stomach.

Therefore, three terms used to describe organisms such as cows are:

Answer:

To analyze the diversity of various chloroplast solution.

Explanation:

Chromatography is a separation technique used to analyze and compare two or more complex and colored solutions or mixtures. There are several types of chromatography like paper and thin-layer chromatography. The latter is used to separate and analyze two mixtures, applied at an angle of 90 degrees from each other while the former is used to separate multiple non-volatile solutions.

Answer:

A. a disturbance that transfers energy

Answer: See Below

Explanation:

25,000,000km = 1cm

In other words 25 million km = 1 cm

Mercury- 57.91 million kilometers

57.91 million km * 1 cm/ 25 million km = 57.91/ 25 cm = 2.3164 cm

Venus - 108.2 million kilometers

108.2 million km * 1 cm/ 25 million km = 108.2 /25 cm =4.328 cm

Earth - 150 million kilometers

150 million km * 1 cm/ 25 million km =150/25 cm = 6 cm

Mars- 227.9 million kilometers

227 .9 million km * 1 cm/ 25 million km = 227.9/25 cm =9.116 cm

Jupiter- 778.5 million kilometers

778.5 km * 1 cm/ 25 million km = 778.5/25 cm =31.14 cm

Saturn- 1.434 billion kilometers

1.434 billion * 1000 million/1 billion = 1434 million

= 1434 million km * 1 cm/ 25 million km =1434/25 cm =57.36 cm

Uranus- 2.871 billion kilometers

2.871 billion * 1000 million/1 billion = 2871 million

2871 million km * 1 cm/ 25 million km =2871/25 cm =114.84 cm

Neptune - 4.495 billion kilometers

4.495 billion * 1000 million/1 billion = 4495million

4495 million km * 1 cm/ 25 million km =4495/25 cm =179.8 cm

Answer:

The blank is SOURCES

Explanation:

Sources of energy can either be RENEWABLE OR NON-RENEWABLE. Renewable sources of energy are those sources which are easy to replenish while non-renewable sources are difficult to replenish after being exhausted.

Biomass, which comes from plants and animals are considered to be SOURCES of renewable energy because they renewable energy because they take time to grow and require careful planning to ensure continued supply. Trees get their biomass from sun energy, which is a renewable source of energy.

Answer:

slower sources

Answer:

The correct answer is - The axis must be tilted at a certain angle that."  remains unchanged.

Explanation:

On the earth there ae many seasons but there are four major season, winter, summer, spring and autumn. The main reason that leads to all four season is the tilt of the sun at a specific angle that remain unchanged  which leads to change in the distance to the sun at specific time of the year which result in different rays of sun the part. So, whatever hemisphere or part tilted towards the sun leads to different season for instance:

North pole tilted towards the sun - summer in northern hemisphere

south pole tilted towards the sun -  winter in northern hemisphere

Answer:

The axis must be tilted at a certain angle that remains unchanged.

Speedup the reaction.

Explanation:

Glucose isomerase is a type of enzyme that is responsible for the catalyzing the reaction of converting glucose into fructose. Its main purpose to speedup the chemical reaction between glucose and fructose. Without this enzyme, conversion of glucose into fructose will occur but takes a very long time. In this reaction this enzyme catalyze the reaction without using in the reaction.

Explanation:

Plant growth and development are tightly controlled in response to environmental conditions that influence the availability of photosynthetic carbon in the form of sucrose. Trehalose-6-phosphate (T6P), the precursor of trehalas in the biosynthetic pathway, is an important signalling metabolite that is involved in the regulation of plant growth and development in response to carbon availability. In addition to the plant’s own pathway for trehalas synthesis, formation of T6P or trehalas by pathogens can result in the reprogramming of plant metabolism and development. Developmental processes that are regulated by T6P range from embryo development to leaf senescence. Some of these processes are regulated in interaction with phytohormones, such as auxin. A key interacting factor of T6P signalling in response to the environment is the protein kinase sucrose non-fermenting related kinase-1 (SnRK1), whose catalytic activity is inhibited by T6P. SnRK1 is most likely involved in the adjustment of metabolism and growth in response to starvation. The transcription factor bZIP11 has recently been identified as a new player in the T6P/SnRK1 regulatory pathway. By inhibiting SnRK1, T6P promotes biosynthetic reactions. This regulation has important consequences for crop production, for example, in the developing wheat grain and during the growth of potato tubers.

Answer:

Due to the presence of dominant allele.

Explanation:

This type of blood is prevalent even if two recessive alleles are present because the allele of blood type O is dominant as compared to other two recessive allele. Due to dominance of the blood type O, the blood type of next generation will also be type O. we know that only the dominant allele will appear in the offspring so that's why the Peruvian Indians have blood type O.

Answer:

The prostate is a gland of the male urogenital system, it is located below the bladder, in front of the rectum and is crossed by the urethra. In this way the urine leaves the bladder, crossing the prostate, until it is expelled. One of the most important functions of this gland is to provide nutrients for the maturation of the sperm.

Explanation:

The prostate gland is made up of 30-50 glands that empty their contents into the prostatic urethra (the tube that connects the prostate gland with the bladder urethra). Most cancers develop in the peripheral area of ​​the gland, that is, the outermost area of ​​it and is the one that can be felt with the finger. The entire organ is surrounded by a fibrous prostatic capsule.The prostate because it is located below the bladder and starting from it, is crossed by the urethra which is a tube that carries urine from the bladder to the outside. In turn, the prostate is crossed by another tube that comes from the seminal vesicles, which are glands whose mission is to provide nutritional elements to the semen and the vas deferens, which are tubes that start from the testicles and mainly lead the sperm to the outside.
