The ocean is a three-dimensional environment. Explain how this kind of living space impacts diverse forms of marine life.

Many physical, environmental, and biotic processes vary widely across depths. In recent years, human activities, such as oil drilling, mining, and fishing are rapidly expanding into deeper frontier ocean areas, where much of the biodiversity remains unknown. Most current conservation actions, management decisions and policies of both the pelagic and benthic domains do not explicitly incorporate the 3-D nature of the oceans and are still based on a two-dimensional approach. Here, we review current advances in marine research and conservation, aiming to advance towards incorporating the third dimension in marine systematic conservation planning. We highlight the importance and potential of vertical conservation planning and zoning from the sea surface to the seafloor. We propose that undertaking marine conservation, management and environmental decisions in 3-D has the potential to revolutionize marine conservation research, practice and legislation.

Answer:

1) an increase in arterial blood pressure

Explanation:

Blood pressure is not an accurate predictor of a heart attack. Sometimes a heart attack can cause an increase or decrease in blood pressure, but having a change in blood pressure reading doesn't always mean it's heart-related.

What is the best biological definition of species

Alenkinab [10]

A group of closely related organisms that are very similar to each other and are usually capable of interbreeding and producing fertile offspring. The species is the fundamental category of taxonomic classification, ranking below a genus or subgenus. Species names are represented in binomial nomenclature by an uncapitalized Latin adjective or noun following a capitalized genus name, as in Ananas comosus, the pineapple, and Equus caballus, the horse.
2. Logic A class of individuals or objects grouped by virtue of their common attributes and assigned a common name; a division subordinate to a genus.
3. Chemistry A set of atoms, molecules, ions, or other chemical entities that possess the same distinct characteristics with respect to a chemical process or measurement.

In guinea pigs, dark hair (D) is dominant over light hair (d) and curly hair (C) is dominant over smooth hair (c). Complete a di

1. The Punnett square should be laid down in a table of two entries. On the top entry, the possible alleles of one of the parents, and on the other entry, the possible alleles of the other parent, which will be the same as both have the same genotype. The possible alleles for both parents would be: DC, Dc, dC, and dc. On the actual table's body, all alleles should be crossed from one entry and the other obtaining the possible genotypes of the offspring and their proportions, and, therefore, the possible phenotypes and their proportions.

2. By the Punnett square (attached is an example of it), we are able to identify that all possible genotypes have a 1/8 likelihood to happen, besides the genotypes that are homozygous for both alleles (whether dominant or recessive on both traits, or dominant on one trait and recessive on the other) which have a 1/16 likelihood to happen, and those that are equal to the parents (dihybrid) with a 1/4 likelihood to happen.
DDCC, 1/16; DDCc, 1/8; DdCC, 1/8; DDcc, 1/16; DdCc, 1/4; Ddcc, 1/8; ddCC, 1/16; ddCc, 1/8; ddcc, 1/16.

3. Dark and curly hair corresponds to 9/16 of all the offspring. These traits are dominant, and, therefore, are the ones that are present depending solely on the presence of one dominant allele on each trait.
Dark and smooth hair have a likelihood of 3/16 - all those that are homozygous recessive for smooth hair but still have, at least, one dominant allele for dark hair.
Light and curly hair have a likelihood of 3/16 - all those that are homozygous recessive for light hair but still have, at least, one dominant allele for curly hair.
Light and smooth hair have a 1/16 likelihood to occur, which corresponds to the only possible full homozygous recessive genotype.

What event could disrupt one or more body systems?

Serggg [28]

An event that could disrupt one or more body systems is a HEAD TRAUMA. When we say head trauma, this is an injury which affects the scalp, the skull or even the brain. When the brain is greatly affected, all of the other systems in the body would not function well since it is the brain is the center of the coordination of the systems. Hope this answer helps.
