Answer:

The percentage of people carrying sickle cell gene increases.

Explanation:

People carrying the Sickle Cell gene have low chance of Malaria because the sickle cell enables the body to detoxify abnormal red blood cells from the body. When the malarial parasite attacks on the cells of the body, the molecular machinery for cleaning up the waste is already present in the body.  Those places where malaria is common, the people having sickle cell because the sickle cell show resistance against malarial disease.

Answer:

It is D

Explanation:

Trust me I've taken it already, and plus it talks about it not being in the water.

In the given instance, the ecological service which is providing the marsh is the water purification. Thus, the correct option will be D.

Ecological services or ecosystem services are the many and varied benefits which the humans are provided or get from the natural environment and the healthy ecosystems. Such ecosystems include, for example, the agroecosystems, forest ecosystem, grassland ecosystems, and also the aquatic ecosystems.

A group of researchers are monitoring the health of a salt marsh. They measure high levels of nutrients in the sediment but not in the water samples. In this instance, the ecological service which is providing marsh is the water purification.

Therefore, the correct option is D.

Explanation:

Answer:

Vascular plants, also known as tracheophytes, are plants found on land that have lignified tissues for conducting water and minerals throughout the body of the plant.

1. These lignified tissues are also called vascular tissue and consist of water-conducting xylem tissue and food-conducting phloem tissue.

2. Vascular tissue forms a central column, also called stele, through the plant axis for the transport of different substances.

3. Vascular plants are said to have a true stem, leaves, and roots due to the presence of vascular tissues.

4. The root is a true root that enables the plant to anchor onto the soil and gets nutrients from it.

5. The leaves are broad and have stomata that work for gas exchange and support transpiration.

6. The stem of vascular plants is multilayered with vascular tissue that helps in the protection and conduction of food and water.

7. The arrangement of these issues might be different in a different group of plants as it depends on the pattern of division of cells.

8. The xylem is composed of non-living matter, tracheids, and vesicles, hardened by lignin that provides a stiff structure to the tissue. 9. The phloem, on the other hand, contains living sieve elements that are not lignified.

10. Vascular plants are capable of surviving on land due to their ability to transport food, water, and mineral to different parts of the plant by creating pressure through the tissues.

11. Besides, they also have several modifications that facilitate their survival on land.

12. Another essential characteristic of vascular plants is that the principal generation phase in these plants is the sporophytic phase where they produce diploid spores.

13. Vascular plants are tall and large in size compared to the non-vascular plants because of their ability to transport necessary substances to all parts of the body via vascular tissue.

14. It is believed that vascular plants are a more evolved version of non-vascular plants and thus came later in the evolutionary history.

15. Vascular plants are divided into two groups; non-seed plants or lower vascular plants or cryptograms and seed plants or higher vascular plants or phanerogams.

16. The lower vascular plants include plants like ferns that although are adapted to survive on land still have some characteristics of their aquatic ancestry. These plants belong to the group Pteridophyta.

17. The higher vascular plants are numerous and extremely diverse and are further divided into different subgroups.

18.Some examples of vascular plants include maize, mustard, rose, cycad, ferns, clubmosses, grasses, etc.

Answer:

Definition of nonvascular plant

: a simple, low-growing, nonflowering plant (such as a moss or liverwort) that lacks specialized conducting channels for transporting water and nutrients

vascular plants have lignified tissues for conducting water and minerals throughout the plant.

The correct answer is 4. They convert salt and iron into energy and nutrients.

Explanation

Xenophiophores are large single-celled organisms generally found deep in the deep sea. They are characterized by being very delicate organisms, which makes it difficult for scientists who intend to study them since they are easily damaged by manipulation. However, in the studies that have been carried out on these organisms, it has been found that they are irreplaceable agents in the sediment deposition process and the maintenance of the biological diversity of benthic organisms. Also, it has been shown that in the areas where these organisms are found there are three to four times more benthic crustaceans, echinoderms, and mollusks than the equivalent areas not inhabited by these organisms. On the other hand, none of these studies has proven that They convert salt and iron into energy and nutrients. Therefore, the correct answer is 4. They convert salt and iron into energy and nutrients.

Algae provides more energy to the Box Turtle population.

If you see the bottom of the chain, Algae, whether the turtles eat it or not, also provides energy/food/resource for other forms of energy the turtles can consume, it's the base of the chain.

The answer is not aquatic insects because they do not supply as energy to as many sources as algae.

The organism to be identified

Explanation:

To identify the genetic makeup of an unknown organism, the nucleotide sequences fond in the Deoxyribonucleotide (DNA) of a known organism is matched to the DNA of some known organisms. If there is a certain degree of sameness in most of the matched parts, then the unknown organism can be said to be related to the known organism. This is a comparative study.

To carry out this identification, items used include; primers, the PCR machine, test tubes, DNA polymerase, free nucleotides, etc.

Explanation:

Answer: D. Genetic mutation

Explanation:

For evolution to occur, there must be a genetic mutation in the genome of an organism such that a new allele is formed.

If this mutation occurred in the sperm and/or the ovum, the mutation will then be passed on through reproduction to the next generation. This leads to more of the subsequent generations having that mutation thereby leading to evolution.
