If you are observing worms, ants, and caterpillars, you are studying a biological species. Thus, the correct option is B.

What is Biological species?

Biological species may be defined as a cluster of organisms that can reproduce with one another in nature and produce fertile offspring.

A Community may be defined as a group of individuals belonging to different species living in the same area. A Population may be defined as the number of the same species living in the same area at a particular time.

Here, worms, ants, and caterpillars are organisms of different species with different characteristics such as mode of nutrition, reproduction, and response to the environment.

The biological species are considered as an integral part or component of an ecosystem. The greater the biodiversity in an ecosystem, the greater the stability of the species within that ecosystem.

Therefore, if you are observing worms, ants, and caterpillars, you are studying a biological species. Thus, the correct option is B.

What is biological hierarchy?

Biological hierarchy refers to the organization of living organisms into a series of levels, each level being more complex than the one below it. The biological hierarchy begins with the smallest unit of life, which is the cell, and progresses upward to include tissues, organs, organ systems, organisms, populations, communities, ecosystems, and ultimately the biosphere.

Each level of the biological hierarchy is characterized by different properties and interactions. For example, cells are the basic unit of life and perform all the essential functions of an organism. Tissues are groups of cells that work together to perform a specific function, such as muscle tissue, which is responsible for movement. Organs are structures made up of tissues that work together to perform a specific function, such as the heart, which pumps blood throughout the body.

(6 marks)

Answers

Answer:

Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in. Red blood cells are responsible for carrying oxygen and carbon dioxide. Platelets are responsible for blood clotting. White blood cells are part of the immune system and function in immune response.

Blood is important for regulation of the body’s pH, temperature, osmotic pressure, the circulation of nutrients and removal of waste, the distribution of hormones from endocrine glands, and the elimination of excess heat; it also contains components for blood clotting. Blood is made of of several components, including red blood cells, white blood cells, platelets, and the plasma, which contains coagulation factors and serum.

Two humans mate who are heterozygous for earlobe shape where attached earlobes (A) are dominant to free earlobes (a), and earwax quality where dry earwax (e) is recessive to wet earwax (E ). What is the probability that their first child will have dry earwax and attached earlobes

Answers

Answer:

3/16

Explanation:

This question involves two different genes coding for earlobe shape and earwax quality. The alleles for attached earlobes (A) and wet earwax (E) are dominant over the alleles for free earlobes (a) and dry earwax (e).

According to this question, two humans mate who are heterozygous for both genes i.e. AaEe × AeEe. Each parent will produce the following gametes: AE, Ae, aE, ae.

Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:

* Attached earlobe, wet earwax (A_E_) = 9/16

* Attached earlobe, dry earwax (A_ee) = 3/16

* Free earlobe, wet earwax (aaE_) = 3/16

* Free earlobe, dry earwax (aaee) = 1/16

Hence, the probability of these parents having their first child with dry earwax (ee) and attached earlobes (A_) i.e. genotype A_ee is 3/16.
