Answer:
Aerobic to lactic acid fermentation pathway
Explanation:
ATP, which is the usable form of energy in living cells, is obtained via a process called RESPIRATION. However, aerobic respiration requires a constant supply of oxygen to occur. Hence, during an intense exercise where the supply of oxygen is low, the muscle cell has to switch from the respiration pathway that requires oxygen to one that doesn't.
Fermentation is a kind of cellular respiration that does not require oxygen to occur. In the muscle cells of animals (humans inclusive), lactic acid is the product of the fermentation process, hence, it is called LACTIC ACID FERMENTATION. This means that the muscle cells, in a low supply of oxygen, will switch from AEROBIC to LACTIC ACID fermentation pathway.

Answer:
B. Bald eagles are hunted until near extinction, population recovers
Explanation:
A bottleneck effect can arise when the population of a species is drastically reduced by an occurrence. Human activities plays a major role in regard to creating a bottleneck effect in our present day. Human activities such as overhunting result into bottleneck effect. When overhunting reduces the population of a particular species, the few individuals left would have a reduced genetic variation which is not representative of the original population. The few individuals left further reproduces individuals of their kind carrying a genetic composition that is different from the original gene composition of the old population.
The case of the hunting of bald eagles until near extinction before they begin to recover is a perfect case of the bottleneck effect. Only a small proportion of the eagles original population survives. Generic variation reduces. The genetic variation in the new population of the bald eagles will be different from that of the original population.

its because greenhouse effect is a natural process which warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.
The continental crust covers ____ of the earth's surface a. 40% b. 50% C. 60% d. 70%
Answer:
a. 40 percent
Explanation:
Answer:
a. 40%
Explanation:
The continental crust covers 40% of the Earth's surface.
At 25 to 70 km, continental crust is considerably thicker than oceanic crust, which has an average thickness of around 7–10 km. About 40% of Earth's surface area and about 70% of the volume of the Earth's crust is the continental crust. Most continental crust is dry land above sea level.

What is an Obligate anaerobe? How do obligate anaerobes, like the bacteria C. Botulinum, get energy ?
Answer:
See the answer below
Explanation:
Obligate anaerobes are microbes that can only survive in oxygen-deficient environments. They are killed by the normal atmospheric level of oxygen and will only thrive in environments whose oxygen levels are lower than that of normal atmospheric level.
Obligate bacteria such as Clostridium botulinum obtain their energy through anaerobic respiration processes such as fermentation and anaerobic respiration. During this process of fermentation, the lactic acid pathway is mostly used but other fermentation pathways such as propionic acid, mixed acid, acetogenesis, and methanogenesis pathways can be used.

Which statement about inheritance is true?
Girls get most of their traits from their moms; boys get most of their traits from their dads.
Male offspring will always have an X-linked genetic disease if the mom is a carrier.
Fathers always determine the gender of the offspring in humans.
Males never have Y chromosomes.
Answer:
The correct answer is the third statement.
Explanation:
In humans, the males possess one X and one Y chromosome, while the females possess two X chromosomes. Thus, the female always donates X chromosome to the gamete. In any case, the female always generates a similar kind of gamete. While the male either pass X or the Y chromosome to the progeny.
When the gamete with the X chromosome combines with the female gamete than the offspring would possess XX chromosomes and will be a female. On the other hand, when the gamete comprising the Y chromosome combines with the female gamete than the offspring would possess the XY chromosome and will be a male. Thus, it is the father who determines the gender of the offspring.
This is wrong. Parents gender does not affect traits passed on.
Males never have Y chromosomes.This is wrong, Males have to have a Y chromosome. (XY)
Male offspring will always have an X-linked genetic disease if the mom is a carrier.This is wrong. The male offspring have a 50/50 chance if the mother is a carrier, if she has the deseace than all the sons will have the decease.
Correct answerFathers always determine the gender of the offspring in humans.This is because the mom is XX and the dad is XY. The mom gives the X in the gene, and the dad gives the X for daughters (X,X) and gives the sons a Y (X,Y) Males are always XY.
If the mom is a carrier, h, then it will get passed down 50% of the time, and when it gets passed down to the males, they wiill have the deseace. If the mom passes the deacease down to the daughters, 50% will be a carrier too if the dad does not have the deseace. If the dad has the deacease, than 50% of the daughters will have the deacease, and the other 50% will be carrier, and still, 50% of the sons will have the deacease, while the other 50% will be completely clean. So in total 25% of the offspring will be a carrier, 50% will have the deacease, and the other 25% will not have the deacease or be a carrier.
when measuring the blood pressure, the cuff is deflated until two consecutive beats are heard through the stethoscope. This measurement reflects
Answer: Systolic pressure.
Explanation:
Every time the heart beats, it pumps blood into the arteries, which are vessels through which blood circulates from your heart to your tissues with the oxygen and nutrients they need. Blood pressure is the force of the blood pushing against the walls of the arteries, and is highest when the heart beats, pumping blood, which is measured as systolic pressure (i.e., when the heart contracts). On the other hand, diastolic blood pressure refers to the pressure of blood in the artery when the heart relaxes between beats (i.e., when the heart relaxes). Since there are two types of pressures, blood pressure readings are given in two numbers, with the top number being the systolic pressure and the bottom number being the diastolic pressure.
For example, if the systolic pressure measured in a person is 125 millimeters of mercury (mm Hg) and the diastolic pressure is 85 mm Hg, the blood pressure is recorded as 125/85.
So, the systolic blood pressure is registered with the stethoscope when the cuff is deflated. When two heartbeats are heard, the pressure gauge reading is recorded. When the heartbeat ceases, the cuff pressure is released and the diastolic pressure is measured at this time.

Cigarette smoke contains carbon monoxide. Explain how this
would affect the normal functioning of red blood cells in a person who
smokes cigarettes.
Answer: Carbon Monoxide is a very harmful and toxic gas which is formed from incomplete combustion of carbon.
Explanation: red blood cells contain haemoglobin ,which are responsible for carrying oxygen into our body system. So oxygen combines with haemagoblin to form oxyhaemogoblin in the red blood cells .
so if a person starts to intake cigarettes which contain high amounts of carbon monoxide ,it reduces oxyhaemogoblin formation because it binds very tightly to the haemogoblin .then carboxyhaemogoblin is formed and its permanent so causing reduction in aerobic respiration, and reduction in oxygen transport and causing damages to heart muscles.

A. The pea plants were very inexpensive.
B. Most pea plants die after producing seeds.
C. Having more samples gave him results that were closer to the predicted ratios.
D. Using more plants made the experiments take less time.
Having more samples gave him results that were closer to the predicted ratios.Mendel's experiments involved studying the inheritance of traits in pea plants. By carefully crossing different varieties of pea plants and observing the traits of their offspring, he was able to formulate the laws of inheritance that are still used today.
What does Mendel's experiments involves?Mendel's experiments involved observing the inheritance of traits in pea plants, which were controlled by genes.
By studying a large sample size of 28,000 pea plants, he was able to obtain data that was much more reliable and accurate. This is because the larger the sample size, the closer the results will be to the expected outcomes or predicted ratios, and any anomalies or errors would be minimized.
This is an important principle in statistics and scientific research, and it helps to ensure the validity and generalizability of the findings.
Additionally, by using such a large number of plants, Mendel was able to minimize the impact of any outliers or anomalous results that might have occurred in a smaller sample. This helped to ensure that his results were as accurate and reliable as possible.

In a two-point test cross, 36 of the offspring were recombinant types. The remaining 64 offspring were parental types. How many map units separate the two loci
Answer:
36
Explanation:
A two-point test-cross is a cross between an individual with a double heterozygote genotype and a homo-zygous recessive individual in order to determine the recombination frequency between two linked genes. In genetics, one map unit (m.u.) can be defined as the measure of the distance (i.e., genetic distance instead of physical distance) between genes for which one (1) product of meiosis in one hundred (100) is recombinant. In this case, 36 of the offspring have the recombinant phenotype, while the remaining 64 offspring are not recombinant, and therefore both genes are separated by 36 mu (64 + 36 = 100 >> 36 mu).
The distance between two genes is usually expressed in map units. In the exposed example, 36 MU separates the two loci.
----------------------------------
The map unit is used to express the distance between a pair of genes.
To interpret it, we need to consider that for every 100 meiotic products, one of them results in a recombinant product.
The genetic distance will result from multiplying the recombination frequency by 100 and expressing it in map units (MU).
To calculate the recombination frequency we will use the next formula:
P = Recombinant number / Total of individuals.
We know that
Recombinant number = 36Parental number = 64Total number of individuals = 36 + 64 = 100 individualsSo now, all we need to do is to replace the terms by their values
P = Recombinant number / Total of individuals
P = 36 / 100
P = 0.36 ⇒ Recombination frequency
Now we need to get the distance between genes, expressed in Map Units.
P = 0.36
Distance in MU = P x 100 = 0.36 x 100 = 36 MU.
So, 36 MU separates the two loci.
