E. sexual selection

Answers

Answer 1

Answer:

1. D (In population genetics, gene flow is the transfer of genetic material from one population to another.)

2. C (Genetic drift may cause gene variants to disappear completely and thereby reduce genetic variation. It can also cause initially rare alleles to become much more frequent and even fixed. When there are few copies of an allele, the effect of genetic drift is larger, and when there are many copies the effect is smaller.).

3. A  and also E (Individuals with inherited characteristics that allow them to best compete for limited resources will survive and have more offspring than those individuals with variations that are less able to compete. Because characteristics are inherited, these traits will be better represented in the next generation.)

4. D (Gene flow can increase fitness but if it happens in another environment, it decreases the adaptability. If alleles are advantageous, the offsprings' inheritance increases.

5. B (Mutations are the main source of alleles)

You've been tasked to study the movements of condensed chromosomes during cell division.
You have access to a magnifying glass, a standard light microscope, a scanning electron
microscope and a transmission electron microscope. Which piece of equipment would you choose
and why? Also why would you NOT choose the others? (max 50 words)

Answers

In order to see something as small as a chromosome, It is necessary to employ the use of a scanning electron microscope.

The question states that we wish to study the movements of condensed chromosomes during cellular division. This means that we will need a scope capable of not only looking inside of a cell but even inside of the nucleus of a cell, an extremely minute space.

Logically, a magnifying glass will not be able to accomplish this given that it only allows us to see macroscopic elements, many hundreds of times bigger than what we wish to observe. We run into similar limitations with standard light and transmission microscopes. Although these allow us to see things on a microscopic level, they fall short of the desired capability.

Though the transmission microscope can see even smaller elements than a standard light microscope, both are limited to the surface of cells. The SEM or scanning electron microscope, on the other hand, allows the user to see elements down to 0.1 nanometers in size. Given that chromosomes are between 10 and 30 nanometers in size, we can use this microscope for the desired study.

Which structural data is normally used to classify mosses into the category Bryophyta?(1 point)

They are large.


They lack roots.


They produce flowers.


They produce seeds.

Answers

Answer:

They lack roots

Explanation:

The structural data which is normally used to classify mosses into the category Bryophyta is that they lack roots. Thus, the correct option for this question is B.

What are the characteristics of Bryophyta?

The characteristics of the Bryophyta are as follows:

The plant body is mostly thallus-like, i.e. erect or prostate.They are generally attached or linked to the substratum by rhizoids. They significantly lack true vegetative structure. The plants are generally green and have chloroplast.They express an autotrophic mode of nutrition.Vascular tissues like the xylem and phloem are completely absent.

It is known that Bryophytes include embryophytes like hornworts, liverworts, and mosses. These are very small plants that remarkably grow in shady or damp areas where there is an enormous amount of mud is present.

Bryophytes have no roots, leaves, or stems. This characteristic is the root foundation or evidence that is used to classify mosses into the category of Bryophyta.

Therefore, the correct option for this question is B.

Describe the elements and compounds of coal being mined

Answers

Answer:

The organic compounds in coal are composed of the elements carbon, hydrogen, oxygen, nitrogen, sulfur, and trace amounts of a variety of other elements

Coal is a mixture of organic compounds and minerals formed from ancient plant material, primarily composed of carbon, hydrogen, and impurities like sulfur and nitrogen.

Coal is a mixture of organic compounds and minerals, resulting from the decomposition of ancient plant material over millions of years. It primarily consists of carbon, hydrogen, oxygen, nitrogen, and sulfur. Carbon, the dominant organic compound, makes up a substantial part of coal's composition, with hydrogen and oxygen occurring in lesser amounts.

Nitrogen and sulfur are present as impurities, in the form of organic compounds and mineral components. Coal also contains inorganic minerals like quartz, clay, and pyrite, contributing to its ash content. Trace elements, such as mercury, arsenic, and lead, are present in low concentrations. The exact composition varies based on coal type and location, influencing its energy content and environmental impacts.

Explanation:

but its your own opinion

Answer: GMOs are generally though of as bad

Explanation: GMO stands for Genetically Modified Organism.

People take genes from one plant, lets say from a plant that can withstand cold temperatures, and puts it into another plant. This can give the gene of withstanding cold temperatures to the new plant.

A long time ago people would breed plants until they got traits that they like. This takes a very long time. Now with GMOs, you can get the traits you want much faster.

People are concerned with GMOs for allergies, cancer, and environmental harm. Current research hasn't outlined too many risks of GMOs yet as long-term research is still needed.

Answers

It is constant over equal periods of time, in accordance with Kepler's second law of motion. The right response is a.

It is constant if the planet moves at a constant speed. Option C

Describe Kepler's law.?

The orbits of planets around the Sun are described by Johannes Kepler's laws of planetary motion, which were published between 1609 and 1619.

Kepler's second rule of planetary motion gives an explanation for the speed of a planet in an elliptical orbit around the Sun.

It asserts that similar areas are moved in equal lengths of time along a line drawn between the Sun and the planet.

As a consequence, the planet moves faster as it gets closer to the Sun and slower as it moves further away.

The transition from geocentrism to heliocentrism was ushered in by Kepler's laws of planetary motion.

Together with Earth, they provide the first quantifiable connection between the planets. Additionally, they depict a period when the key issues of the day were evolving.
