What can we do to make it possible so that everyone can live off of the earths ressources

Answers

We could possibly use water as a fuel source, rather than fossil fuels (which are limited)

Science has already developed something of the sort, and with using water as a fuel source for say vehicles and such, it's inevitable for a positive change to happen because there would be less carbon monoxide; which means less polution.

After chromosomes are formed, during which phase of mitosis do the chromosomes attach to the spindle fibers by their centromeres? 1. anaphase
2. prophase
3. metaphase
4. telophase

Answers

4.Metaphase
All of the chromosomes are aligned midway between thespindle poles. A spindle is a dynamic network of microtubules thatattaches to and moves chromosomes during nuclear division. Microtubulesattach each chromatid to one of the spindle poles, and its sister to theopposite pole.

Chromosomes attach to spindle fibres by their centromeres during metaphase of mitosis.

Further Explanation:

Interphase is the resting phase or metabolic phase of a cell where it prepares itself for the cell division process. Interphase comprises of sub-phases namely, Gap1 phase, Synthesis phase and Gap2 phase. G1 is the first gap phase where a cell grows larger in size and the cytoplasm volume increases as more organelles are produced. During Synthesis phase, the strands of DNA replicates. G2 is another gap phase in which the cell becomes much larger in size and this phase is followed by mitosis where cell division occurs.

Mitosis or somatic cell division is comprised of four phases which includes prophase, metaphase, anaphase and telophase. A somatic cell divides to give rise to two identical daughter cells where each cell contains exact copy of each chromosomes present in the parent cell.  In the prophase, the envelope that covers the nucleus and nucleolus disappears and chromosomes become visible by forming two chromatids attached to centromere.

In the metaphase, chromosomes alignment at the metaphase plate occurs and spindle fibres attach to the centromere. Spindle fibres pull the chromatids away from the metaphase plate towards the opposite poles of the cell during anaphase. In the telophase, nuclear membrane reforms, chromosomes decondense and nuclear membrane reforms around each daughter nuclei. The cytokinesis is the final stage of cell division process where the parent cell is pinched off to result in two daughter cells.

Select the CORRECT statement about the pharynx. A. The palatine tonsils are embedded in the lateral walls of the nasopharynx.
B. The pharynx contains the vocal cords.
C. The pharyngeal tonsil is located in the laryngopharynx.
D. The auditory tube drains into the nasopharynx.

Answers

Answer:

D. The auditory tube drains into the nasopharynx.

Explanation:

The auditory tubes, commonly known as eustachian tubes have their pharyngeal openings in the lateral wall of the nasopharynx. Auditory tubes also prevent the mucus to enter the middle ear by channelizing it into the nasopharynx. This clearance of mucus does not allow any infection to spread to the middle ear.

Final answer:

The correct statement about the pharynx is that the auditory tube drains into the nasopharynx.

Explanation:

The correct statement about the pharynx is D. The auditory tube drains into the nasopharynx.

The palatine tonsils are actually embedded in the lateral walls of the oropharynx, not the nasopharynx. The pharynx contains the larynx, not the vocal cords. And the pharyngeal tonsil is located in the nasopharynx, not the laryngopharynx.

The genetic information in human and chimpanzee DNA shows a high degree of similarity, as humans share about 96-99% of their DNA code with chimpanzees. What is an explanation for this similarity?

Answers

This similarity can be explained by Charles Darwin's Theory of Evolution. Humans and chimpanzees share a common ancestor wherein a number of million years ago, due to adaptation of their environment, human species branched out and eventually evolved into Homo sapiens. 

Answer:

The correct answer would be common ancestry.

Common ancestry means that different species have been established from a single parent species or population.

Organisms which share more recent common ancestors tend to have more similarity as compared to the organisms which share an older ancestor.

Humans and chimpanzees also believed to evolved from a common ancestor around 6-7 million years ago.

It is the reason why humans and chimpanzees share around 96-99 percent of the DNA.
