How did the concept of biodiversity originally become more excepted in the scientific community?
Answer:
The Importance of Biodiversity
Increase ecosystem productivity; each species in an ecosystem has a specific niche—a role to play.
Support a larger number of plant species and, therefore, a greater variety of crops.
Protect freshwater resources.
Promote soils formation and protection.
Provide for nutrient storage and recycling.

In horses, black coat color is influenced by the dominant allele (B) and chestnut coat color by the recessive allele (b). Trotting gait is due to a dominant gene (T), pacing gait to the recessive allele (t). What color horse would you use to find out the exact genotype of a black trotter? Explain.
Answer:
Bb or BB and Tt or TT
Explanation:
Black coat could be BB or Bb because it only needs one dominant allele for the trait to show up and the same goes for Tt and TT.
When the environment acts for or against one extreme characteristic, this is an
example of which category of natural selection?
Answer:
Directional selection
Explanation:
occurs when natural selection favors one extreme of continuous variation. Over time, the favored extreme will become more common and the other extreme will be less common or lost.

what is the definition of natrual asexul reprduction?
Answer:
In natural asexual reproduction, roots can give rise to new plants, or plants can propagate using budding or cutting. In grafting, part of a plant is attached to the root system of another plant; the two unite to form a new plant containing the roots of one and the stem and leaf structure of the other.
Explanation:
Mitochondria are cell structures that contain a small quantity of DNA.
Scientists are sequencing the DNA of one particular gene in mitochondria to
help identify different species of many animals including myriapods. The
sequences that they find are called ‘barcodes’.
(i) State the part of the cell that contains most of the DNA.
[1]
(ii) Suggest how DNA barcoding might be useful in the classification of animals,
such as myriapods.
Is this correct guys?
Answer:
Yes its correct.

How does the inheritance of dominant traits differ from the inheritance of recessive traits?
Answer:
Dominant traits are more visible than recessive traits
Give one reason why some people do not approve of using contraceptives. [1]
Answer:
Reasons for failure to continue to use contraception include the following: for some, the risk of producing an unwanted pregnancy adds flavor to the sexual act; some women rationalize their sexual activity, and this usually leads to discontinuation of contraceptive use; failure to change the contraceptive when needs

What is an example of a mutation that is beneficial? *
A. A mutation that deletes part of the DNA, causing an organism to lose its arm.
B. A mutation that allows humans to digest milk and the nutrients in the milk
C. A mutation that ends up doing nothing to the organism
which one ^
Answer:c
Explanation:
B.
A mutation causing an organism to lose its arm would be harmful and a mutation which does nothing is neither harmful nor beneficial.
The answer is B.

When mammals get an infection, their internal body temperature often rises 2 to 3 degrees Celsius. The body gets the energy it needs to react to an infection by -
Answer:
The correct answer is - increasing the rate of cellular respiration in the mitochondria.
Explanation:
During the infection, the body of mammals increases its temperature to kill the pathogens that normally die at high temperatures. To increase the body temperature our body promotes the rate of cellular respiration in the cells to produce more energy.
Cellular respiration is the process that helps in converting stored energy into a form of useable energy for the cell which is ATP. It takes place in the mitochondria of the cell which is called as the powerhouse of the cell and all the function related to energy or ATP is conducted by here.
Which statement best explains how a light wave behaves when moving from air to water?A:it speeds up and bands B:it slows down and bands C:it speeds up and continues straight D:it slows down and continues straight.
Answer:
it speeds up and bends
Explanation:
common sense lol
The statement that best explains how a light wave behaves when moving from air to water is "it slows down and continues straight." That is the last option, i.e., option D, as light travels more slowly in water.
What is the significance of the waves at different mediums?Waves react differently in different mediums, such as when the phenomenon of refraction is used in many optical devices such as lenses, prisms, and mirrors, and these devices change the property of light to slow down and bend when moving from one medium to another. In microscopes and telescopes, the study of light refraction has provided important insights.
Hence, the statement that best explains how a light wave behaves when moving from air to water is "it slows down and continues straight." That is the last option, i.e., option D, as light travels more slowly in water.

What common breeds get affected by gastrotomy?
Answer:
Great Danes, greyhounds and german Shepherds
Explanation:
GDV tends to effect deep chested dog breeds
what general type of mutation has the greatest effect on the protein produce
Answer: The most serious of these mutations will be the insertion of 2 bases. Becasue the genetic code is read in triplets, a 2 base insetion will alter the reading frame of the code causing a frameshift mutation meaning every amino acid after the site of the mutation will be incorrect.

Determine the proper number of chromosomes that would be found in a human cell at each stage of the cell cycle.
Answer: The genetic material of the cell is duplicated during S phase of interphase just as it was with mitosis resulting in 46 chromosomes and 92 chromatids during Prophase I and Metaphase I. However, these chromosomes are not arranged in the same way as they were during mitosis.

Answer:
the correct answer is D
Explanation:
how to do this question plz
Answer:
We are only given one leaf, but the leaves in layer D of the same species would not be identical. Some of them could have deeper indentations or fewer indentations. A wider leaf surface area lets a plant absorb more sunlight, so it would be an advantage if leaves have fewer indentations.
The plants with fewer indentations will reproduce more, passing on their genes for fewer indentations. This repeats for a long time, then plant leaves overall would only have very small indentations (like the leaf for layer B).
Explanation:
There are mutations and variations that make one organism different from another organism, even if they're the same species.
Natural selection is when the environment "chooses" the organisms that have an advantage in the environment to reproduce. Organisms that are selected to reproduce can pass on their genes to future generations.
The deep indentation leaves from layer D were basically "phased out".

which instrument would produce
sound with the longest wavelength?
a. Flute
b. Bass guitar
C. Violin
d. cymbal
Answer: Long wavelengths are the result of a deeper sound since it takes longer for it to travel through a medium. The Bass Guitar is your best bet as it is the lowest sounding instrument, meaning is had the longest wavelength.
