Answer:

$\boxed {\boxed {\sf Nucleic \ acids}}$

Explanation:

Macromolecules are larger molecules made up of smaller building blocks known as monomers. There are 4 major macromolecules that are incredibly important for maintaining life. We are looking for the macromolecule that carries genetic material.

Nucleic Acids 

These include DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). They are made up of nucleotides and store the genetic information in a cell.
This seems to be the correct answer, but let's check the other answer choices to ensure this is correct.

Lipids

These include fats, oils, steroids, and phospholipids. They form cell membranes and hormones, and function as stored energy.

Proteins

These are made of amino acids. They can act as structural components, enzymes, hormones, and more.

Carbohydrates

There are many different kinds: monosaccharides, disaccharides, and polysaccharides. They are used as a form of quick energy.

Nucleic Acids are responsible for carrying the genetic material in a cell.

The population in South Africa is more prone to sickle cell anemia (genotype "ss"). People with genotype "ss" survive only up to

lions [1.4K]

The answer is stabilizing selection.

Sickle-cell anemia is a recessive disorder caused by the presence of two recessive alleles "s", so genotype is "ss". This disorder is characterized by sickle hemoglobin. In an area with malaria, heterozygous individuals "Ss" (with one dominant allele and one recessive allele) have an advantage. These individuals will have both normal and sickle hemoglobin. But pathogen that causes malaria affect only normal hemoglobin, so heterozygous individuals will have half of the hemoglobin resistant to the pathogen and those individuals are resistant to malaria.

Stabilizing selection favors heterozygotes Ss, disruptive selection favors dominant (SS) and recessive (ss) homozygotes, while directional selection favors dominant (SS) or recessive (ss) homozygote. Since in this example, people with genotype Ss (heterozygotes) are in advantage, then this is an example of stabilizing selection.

_____is an interaction between species that affects both species negatively (-/-), as they utilize similar resources.

jolli1 [7]

An interaction between species that affects both species negatively (-/-) , as they utilize similar resources is called as Competition .

Competition :

Competition is a process in which the fitness of individual of one species is significantly lower than that of the individual of same or different species.

Types of competition :

For the necessities of life , it is divided into two types .they are as follows,

A) interspecific competition : it is a competition which occurs between the individuals of two different species having some requirements of life , e.g.,carnivorous animals such as tiger ,lion ,leopard etc .compete for the prey . in the forest habitat ,herbs and trees compete for sunlight , water space , minerals , and biological pollinators .

If the individuals of two different species have sme one or more requirement the the competition becomes very severe e.g., grassland is the common habitat for bison ,dear rabbits ,rats grasshoppers , etc .if thee is short supply of grass due to draught then the competition becomes severe

The survival of the consumers is determined by the quantity of grass required by each species ,ability to change the food and its capacity to migrate to new localities.

B) Intraspecific competition : it occurs between the individuals of the same species .this type of competition is very severe as all the individuals of the same species have almost common requirement of food ,habit etc .besides they also exhibits similar adaptations to fulfill their requirements ,e.g., animals of same species compete for water ,food and mates .

Intraspecific competition is the driving force behind evolution and natural selection .

Thus the Competition only negative impact on environment.

A crop is treated with a pesticide and 98% of the insects are killed. what will most likely happen to the remaining insects?

Marina CMI [18]

The 2% of the insects will begin to reproduce and grow their population exponentially and in time enable the population to recover. This is if the population is large enough to enable random mating. The 98% reduction in population drastically reduces competition for the remaining individuals hence giving them abundant resources for them to thrive.

Which of the following is an example of an adaptation that allows similar species to live in the same environment?

Andrei [34K]

Answer:

B. Both mussels and barnacles live in the tidal ecosystems.

Explanation:

Mussels are small bivalve molluscs that are adapted to both marine and freshwater ecosystems. Barnacles, on the other hand, are arthropods that are adapted to marine ecosystems. However, both are adapted to shallow and tidal zones.

Both organisms are small and have the capacity to live in tidal ecosystems where they thrive and play important ecological roles. For instance, barnacles are filtering organisms, which is extremely important for the food chain, and mussels filter out significant amounts of excess nutrients and metals, that is, they make the water more suitable and clean for organisms to live.

As they are both adapted to tidal ecosystems, this would be an example of an adaptation that allows similar species, in this case mussels and barnacles, to live in the same environment.
