Answer: At low latitudes, near the equator, direct overhead sunlight received all year warms surface waters.
Cold water is also more dense, and as a result heavier, than warm water. Colder water sinks below the warm water at the surface, which contributes to the coldness of the deep ocean.
Explanation:
Answer:
The density of ocean water is so varied, that while there may be a generally considered variation due to temperature, taking random samples in a wide variety of places, thus you can distinguish no real pattern.

What is an allele? View Available Hint(s)for Part A a variety of pea plant used by Mendel an alternative version of a gene the recessive form of a gene the dominant form of a gene a type of chromosome
Answer:
An allele is one of two (or more) versions of a gene. Each individual inherits one allele from each parent. Alleles code for different trait an individual has, such as eye color, skin color, hair type, etc.
Explanation:
Identify the mutation below that would be passed on to a living, fertile offspring if it happened in a parent.(1 point)
DNA replication errors that take place in somatic, or body, cells that are repaired by the cell
UV radiation exposure causes a mutation in a skin cell that results in the formation of cancer
a chromosomal mutation that affects a sperm cell, deactivating a crucial gene involved in development
an insertion mutation in an egg cell that deactivates a gene for hair color, resulting in a viable error
Answer:
an insertion mutation in an egg cell that deactivates a gene for hair color, resulting in a viable error
Answer:
Option 4. an insertion mutation in an egg cell that deactivates a gene for hair color, resulting in a viable error.
Explanation:
Only germline mutations are hereditary in nature i.e., that can be passed on from the parent to the offspring. Examples of hereditary mutation include Sickle cell anemia or hemophilia.Germline mutation: Any noticeable genetic changes in the germ cells of the body that is passed on from the parent to off spring.Mutations such as somatic cell mutation, chromosomal mutation, silent mutations are not hereditary.Option 4 talks about the mutation in egg cells i.e., the reproductive cell which affects the phenotypic traits such as hair color. The change in the phenotypic trait means that it is a genetic mutation of the egg cell as phenotypic changes only occur as a result of genetic mutation. Hence, any detectible mutation in the germ cell can pass on from a parent to offspring.For more information:

Biology cell division
What are the answers to this chart
The cell spends most of the time in the interphase, which is in the G1, S, and G2 phases, and approximately 22 hours out of 24 hours, with the rest being 1–2 hours, are spent in the division phase.
What is the time spent in the cell cycle?
The cell enters the cell cycle, and the first stage is the G1 phase, where the cell grows and spends a lot of time nearly 11 hours and then the cell enters the S phase. In the S phase, the DNA replicates and spends nearly 7 hours, and then in the G2 phase, 3 to 4 hours are spent by the cell, with the remaining 1 to 2 hours spent in the M phase, also called the mitosis or division phase.
Hence, cells spend most of the time in the interphase, which is in the G1, S, and G2 phases, and approximately 22 hours out of 24 hours, with the rest being 1–2 hours, are spent in the division phase.

Explain in your own words what is meant by one of the diagrams below, you only need to choose 1 to talk about. Share as much detail as you can.
The T-Rex diagram relates to the evolution of species on planet Earth.
The following images are shown in this diagram:
A T-Rex dinosaurA drawing of the planet EarthA drawing of grassA drawing of a cowA drawing of a humanThese 5 pictures can be related to finding the main message of the diagram. This diagram can be interpreted as the evolution of species on planet Earth because a dinosaur is shown first, a species that lived millions of years ago.
An image of the Earth is then displayed showing the familiar shape of the continents to demonstrate evolution on the Earth's surface.
Then show the grass because this represents the evolution of plant species that were expanding throughout most of the Earth.
Subsequently, a cow is shown as an example of the mammalian animals that exist today and finally the human who is the product of various evolutionary processes that resulted in the society and the world that we know today.

Greenhouse gases include carbon dioxide and methane.
Answer:
true
Explanation:
are environmental factors more likely to affect genotype or phenotype?
Environmental factors are more likely to affect phenotype than genotype.
Phenotype refers to the observable physical characteristics of an organism, a product of the genetic information contained in the genotype, in accordance with the conditions of the determined environment in which the organism lives.
The phenotype supposes the manifestation of the genotype based on the environmental factors, the traits expressed by the phenotype are behavioral and physical.Regardless of the genotypic information manifested, environmental factors will also shape the phenotype of an organism, since it can suffer accidents, changes or adaptations that a genetically similar individual but in another environment would not suffer.Therefore, we can conclude that the phenotype is the variable expression of a genotype in accordance with the environmental factors.

Answer:

Explanation:
Energy pyhamids, otherwise known as trophic level diagrams, are used to represent the flow of
energy through an ecosystem. An organisms trophic level indicates the organism's position in
the sequence of energy transfers. The bottom, or base, of an energy pyramid is a position
always held by the producers and represents (by far) the largest percentage of biomass for
the food web. The need for such a large biomass of producers is to support the energy
needs for all the organisms at higher trophic levels. Draw and label an energy pyramid for the
following 1 hectare of farmland:
• 30,000,000 MJ of Sunlight (solar energy) reaches ground level during a 150-day growing
season
• 52,164 MJ of energy is stored in the soybeans grown on the hectare of land
1,645 MJ of energy is stored in edible beef by cattlewho eat the soybeans
From the total energy that reaches the ground, 1% is used by producers. The energy transference in the trophic web follows the 10% rule, in which each level uses 10% of the energy stored by the anterior level.
---------------------------------------
Only 1% of the total solar energy that reaches the ground is used by producers, who occupy the first trophic level. From this input of solar energy, it begins a unidirectional energy flow through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is finally dissipated in the environment. At each trophic level, it occurs an energy transfer from one level to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule". This is, as a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time. The progressive reduction of energy determines the number of trophic levels (4 or 5).If 30,000,000 MJ of Sunlight (solar energy) reaches ground, then only 30,000 MJ can be absorbed by primary producers.
5,216.4 MJ from 52,164 MJ of energy stored in the soybeans, are used by cattle.
1,645 MJ of energy is stored in edible beef by cattle who eat the soybeans.
164.5 MJ of this energy is tranferred to the following trophic level.

D)
biodiversity of plant and animal species
Answer:
D
Explanation:
As population grows all the above factors increase expect the biodiversity of animal and plant species.
On a basic level, it is obvious that population increase and per capita income growth are related. Per capita income is simply total income divided by the population. Thus, option D is correct.
What inverse relationship to population growth?When attempting to forecast changes in population size, demographers frequently focus on four essential criteria.
The population's starting age profile (whether it is relatively young or old to begin with), migration, and fertility rates (death rates; life expectancy).
Depending on particular environmental factors, two different patterns of population expansion may manifest: In a perfect, limitless environment, an exponential growth pattern (J curve) manifests itself.
The development of a logistic growth pattern (S curve) occurs when external forces reduce the pace of growth.
Therefore, The gap between the growth rates of income and population is roughly equivalent to the growth rate of per capita income.
