Where does the egg receive its energy from?


options:


a. The ovum contains a large quantity of cytoplasm, which contains nutrients for the first days of development after fertilization. The cytoplasm of the ovum contains over 140 000 mitochondria to produce ATP required for growth.



b. The uterus contains over 140 000 mitochondria to produce ATP and supplies this to the egg for growth.



c. Similar to sperm it receives its energy from fructose through its path to the uterus.



d. The ovum contains a large quantity of fimbria, which contains nutrients for the first days of development after fertilization.

Where Does The Egg Receive Its Energy From?options:a. The Ovum Contains A Large Quantity Of Cytoplasm,

Answers

Answer 1

Answer:

Until attachment to the uterus, the developing organism is on its own. That means it needs to supply its own energy, so the cytoplasm of the human egg cell contains many energy-generating factories called mitochondria. Those mitochondria come only from the mother.

a. The ovum contains a large quantity of cytoplasm, which contains nutrients for the first days of development after fertilization. The cytoplasm of the ovum contains over 140 000 mitochondria to produce ATP required for growth.

(Choice C)
C
Smallest fragment of DNA that traveled the fastest

(Choice D)
D
Largest fragment of DNA that traveled the slowest

Answers

Answer:

C) Smallest fragment of DNA that traveled the fastest

Explanation:

During this gel electrophoresis, DNA passes through a agarose obstacle course, where the poles opposite to wells are positively charged electrodes. Since DNA is negative in charge, when it is placed in wells and electric current is run, DNA will try to run towards the positive end.

Shorter DNA segments can easily  "wiggle" through the pores of the gel whereas, longer DNA segments need to do more "squeezing" to move down the gel.

Therefore, Band X in this figure is the shorter DNA segment as it move through the lane at a faster rate and reaches very far when compared to longer DNA segments.

Smallest fragment of DNA that traveled the fastest. So, the correct option is (C).

What is Gel electrophoresis?

Gel electrophoresis is defined as the technique that is used in laboratories to separate charged molecules such as DNA, RNA and proteins according to their size where the charged molecules move through a gel when an electric current is passed through it.

During gel electrophoresis, the DNA passes through an agarose barrier course, where opposite poles of the wells are positively charged electrodes, so the DNA is negatively charged when it is placed in the wells and an electric current is passed through it. DNA will try to run towards the positive end.

Shorter DNA segments can easily "squeeze" through the pores of the gel, while longer DNA segments require more "squeezing" to move down the gel. Band X in this figure is the short DNA segment as it moves through the lane at a faster rate and reaches much farther than the longer DNA segments.

Thus, smallest fragment of DNA that traveled the fastest. So, the correct option is (C).

As you move up an energy pyramid, all of the following decreases except for

the biomass for the trophic level

the energy at each trophic level

the number of organisms in each trophic level

the average percentage of energy lost as heat

Answers

Answer:

the average percentage of energy lost as heat

Explanation:

An energy pyramid (also called trophic pyramid) is a graphical representation that exhibits how energy flows at each trophic level in a particular ecosystem. In an energy pyramid, it is possible to determine how much energy is available at each trophic level and how energy flows from producers (e.g., photosynthetic plants) to primary consumers (e.g., herbivores), then from primary consumers to the next trophic level (e.g., carnivores), and so successively to all major trophic groups (e.g., higher carnivores). During this chain, energy is lost as heat when it is transferred to the next level, and the average percentage of energy lost increases at each trophic level, thereby less and less energy is available to major trophic groups.

Which does not provide for enhanced genetic mixing?
A.Mix-matching
B.Random segregation
C.Crossing over
D.Fertilization that occurs through sexual reproduction

Answers

Answer:

A. Mix-matching

Explanation:

Sexual reproduction increases genetic variation in offspring by three main mechanisms: 1-random assortment of chromosomes during meiosis 2-genetic recombination, and 3-random fusion of gametes from different parents. In the first place, the pairs of homologous chromosomes are randomly oriented in metaphase I before they separate in Anaphase I. In consequence, daughter gamete cells receive different combinations of chromosomes. Second, recombination (also called crossing over) refers to the interchange of genetic material between non-sister chromatids during prophase I, thereby also increasing genetic variation in daughter cells. Third, the fusion of two haploid cells (i.e., gametes) in diploid organisms results in the formation of a single zygote cell that develops into a new organism, thereby the process of random fertilization between any two gametes generates different diploid zygotes, increasing thus genetic diversity.

how would hemoglobin content differ in a person living in philadelphia compared to someone living in denver

Answers

Answer:

The correct answer is - the difference in altitudes.

Explanation:

The hemoglobin in the person of Denver who lives at a higher altitude than the person who lives in Philadelphia will be much higher. This is due to the fact that at higher elevation or altitude atmospheric pressure decreases that causes hemoglobin to stick to the RBCs and that results in less oxygen level in the body.

To compensate for this low level of oxygen levels hemoglobin content need to be higher in people living at a higher elevation.

Acid rain reacts with calcite present in limestone---> chemical weathering

Explanation:

The root of a huge tree causes cracks in a rocky surface is the example of biological Weathering because in this weathering living organism is involved.  Part of a cliff breaks and falls due to waves of water is the example of mechanical weathering because water enters the small pores of rocks and formed cracks when expands.  Acid rain reacts with calcite present in limestone is a chemical weathering because acid present in rain water is responsible for the degradation and breakdown of rocks.

Mendel used more than 28,000 pea plants in his experiments. Why is it important that he studied such a large sample of pea plants?
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.

Answers

The answer is C. cus the more peas he uses the more accurate the result is

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.
