Explanation:
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
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.
Hepppp!!! The American curl is a type of cat with curled ears. A single gene with two alleles codes for the ear-shape trait. The dominant allele (R) codes for curled ears, and the recessive allele (r) codes for straight ears. If two curled ear cats produce a kitten that has straight ears, what is the genotype of the parent cats? a Rr x Rr b RR x RR c RR x Rr d Rr x rr
Answer:
Rr Rr
Explanation: The parents of the cat have to have an R allele to be a curled cat, but they can't be RR because that is a dominant gene, meaning that the recessive trait cannot happen. This means that the parents have to have a recessive trait, which means that they are heterozygous.

what is meiosis and where does it happen
Answer:
Meiosis only occurs in reproductive cells, as the goal is to create haploid gametes that will be used in fertilization. Meiosis is important to, but not the same as, sexual reproduction. Meiosis is necessary for sexual reproduction to occur, as it results in the formation of gametes (sperm and eggs).

Jayden used the multiplication table below to determine that 8:14 is equivalent to 24:42
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.
I hope this helps

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?
Answer:
The two abiotic conditions in the coral reef that contribute to the high biodiversity are:
TemperatureSunlightWhilst the abiotic factors are
Plant and BacteriaExplanation:
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.

Explanation:
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
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.

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