Living systems are incredibly diverse in size, shape, environment, and behavior. It is estimated that there are between 10 million and 100 million different species. Despite this wide variety of organisms, it remains difficult to define what it means to say something is alive. Which of the following can be described as the smallest living unit?A.) OrganelleB.) DNAC.) ProteinD.) Cell

Answers

Answer:

The correct answer is:

Cell (D.)

Explanation:

The cell is the basic structural, functional and biological unit of a living organism that is the smallest unit of life. It is said to be the building block of life. Being the smallest unit of life, a cell is a collection of organelles and biomolecules that can function independently and still possess the qualities of life. These structures are enclosed in a cytoplasm, within a membrane, and these biomolecules include Nucleic acids (DNA, RNA), proteins etc.

Defined as variation of life on Earth, ____________ is the number and relative abundance of different species.

Answers

Answer: Diversity

Explanation: The earth is composed of different species of organisms spread across various parts and regions of the earth. The idea of having varying classes of species scattered on the earth is called diversity culled from the word diverse, which is used to describe a property of Variation in component. Hence, diversity explains the variation in the number and size of different species, culture and languages (biodiversity) and other components of the human existence. Additionally, the concept of diversity helps us realize the need to respect and embrace our differences in other to foster progressive relationship.

Jayden used the multiplication table below to determine that 8:14 is equivalent to 24:42​

Answers

Answer: They are both equivalent.

I don't see a multiplication table down below, but I get what you're trying to answer.

Explanation:

8:14 and 24:42 are both the same as 8/14 and 24/42. Multiply both the denominator and numerator by 3 since that's how you solve equivalent ratios. If you try 1 and 2, they will not work. 8*3=24 and 14*3= 42, therefore 8:14.

A. Sperm cell
B. Feather cell
C. Skin cell
D. Nerve cell

Answers

Answer:

A. Sperm cell

Explanation:

Mutations are genetic alterations in the nucleotide sequence that form the genome of a given organism. In general, mutations have negative effects (i.e., mutations are generally deleterious), but sometimes these genetic changes may be adaptive (and therefore beneficial). Somatic mutations are genetic alterations acquired by somatic cells (they can not be inherited by the offspring), while germline mutations occur in gametes (sperm and egg) and they can be inherited by the offspring, thereby affecting the progeny of the organism.

What are two abiotic and two biotic conditions in a coral reef that provide the conditions necessary for it to have high biodiversity? How could a disturbance affect the biodiversity of the coral reef?

Answers

Answer:

The two abiotic conditions in the coral reef that contribute to the high biodiversity are:

TemperatureSunlight

Whilst the abiotic factors are

Plant and Bacteria

Explanation:

The coral reef which covers a space of 115,831 square miles (or 30 million hectares os space) is home to a rich diversity of aquatic life (plants and animals alike). Being the largest coral reef on earth a lot of attention is given to it to ensure that its health and functionality is preserved.

The above factors contribute immensely to the stability and operability of the great reef.

The coral reef abounds with many aquatic animals such as crabs, herbivorous fish, sea turtles, sea urchins etc Many of these feed off microscopic plants such as the phytoplankton (that is tiny plants) and microscopic animals referred to as zooplankton. The zooplankton in turn feed off microscopic plant, bacterioplankton and even other zooplankton.

It is easy to see that at the base of the food chain lies Phytoplankton and bacterioplankton. This group require sunlight to thrive.

The smaller herbivorous fish, crabs, sea turtles and urchins on the other hand, constitute food for larger animals such as sharks, Baracuda etc.

It is also important to note that these microscopic life (plant and animals) require a certain temperature to thrive. If the water body in these eco system were to exceed a certain temperature, it is highly doubtful that they would survive. The death the the plant and animal life at the base of the food chain will completely disrupt the entire biodiversity and may even lead to its extinction.

Low genetic diversity within a population of Coachella Valley fringe-toed lizards can lead to _____. faster range expansion for the species lower mortality rates higher birth rates higher rates of birth defects and increased susceptibility to disease

Answers

Answer:

increased susceptibility to disease

Explanation:

The correct answer would be increased susceptibility to disease.

Low genetic diversity within a population means that there are few alleles in the gene pool of the population. The implication is that the population will not be able to evolve in response to disruptive influences. There are few alleles available for natural selection to act on. Hence, the population is more susceptible to external influences such as disease outbreak.

Did the enzymes from Claire's small intestine break down the
protein at a low, normal or high rate?

Answers

Answer: low rate

Explanation:

Claire is a Great Dane who was losing weight despite the fact that she is eating. Claire doesn't have an increase in appetite and also doesn't have enough energy that is required for her to play.

Claire is losing weight because food the enzymes in her body doesn't break down the food that she eats. When compared to a dog that was healthy, the enzymes from Claire's small intestine broke down protein at a low rate.

Small intestine of Claire break down the  protein at a low rate.

The enzymes from Claire's small intestine break down the  protein at a low rate because the proteases is present in a very low amount in the small intestine. The proteases enzyme is responsible for the break down of proteins.

If proteases is present in large amount then the protein present in food is broken down at a faster rate while on the other hand, if the proteases is present in small amount then more time is needed to digest the protein so that's why Claire's small intestine break down the  protein at a low rate.
