Which cards are nucleic acids?

Answer:

The correct option is b

Explanation:

There are four nitrogenous bases that can be found in a DNA molecule; Adenine, Thymine, Guanine and Cytosine. The adenine on one strand can only bond (hydrogen bond) with the thymine on the complimentary strand (to form base pair) and vice versa while the guanine on one strand can only bond (hydrogen bond) with the cytosine on the complementary strand (to form base pairs) and vice versa.

There are three hydrogen bonds between Guanine and cytosine base pair while there are two hydrogen bonds between adenine and thymine base pair; hence, DNA samples with higher guanine-cytosine base pairs denature at a higher temperature than DNA samples with lower guanine-cytosine base pairs or with more adenine-thymine base pairs. This is because, it requires more energy to break the triple bonds between the guanine-cytosine base pairs than the double bonds of adenine-thymine base pairs.

From the description above, we can deduce that the correct option is b

Answer:

0.0556 mL of 90 M HCl would be taken and 9.944 mL distilled water added to make 0.5 M, 10 mL HCl solution.

Explanation:

From the dilution equation:

Initial molarity (m1) x initial volume (v1) = final molarity (m2) x final volume (v2).

In this case, m1 = 90 M, v1 = ?, m2 = 0.5 M, and v2 = 10 mL

v1 = m2 x v2/ m1 = 0.5 x 0.01/90 = 0.0000556 L

v1 = 0.0556 mL

This means that the initial volume of 90 M HCl to be taken is 0.0556 mL. Since the final volume to be prepared is 10 mL,

 10 - 0.0556 = 9.944 mL

Hence, 0.0556 mL of 90 M HCl would be taken and 9.944 mL distilled water added to make 0.5 M, 10 mL HCl solution.

Answer:

Consultation.

Explanation:

Consultation is not included because there is no need for it in US fish and wildlife service. Cooperation, communication and contemplation are needed in order to conserve the US fish and wildlife service in a good manner. Cooperation is required in order to fulfill the common goal and communication between different departments is also necessary. contemplation refers to examination and inspection which is very important for achieving the goal.

Answer:

asparagine

Explanation:

take a look at the graph attached, it helps identify codon sequences.

The codon AAC codes for the amino acid asparagine. Asparagine is a non-polar, neutral amino acid that is found in all living cells. Hence option C is correct.

It is involved in a variety of cellular processes, including protein synthesis, cell signaling, and energy metabolism.

The other answer choices are incorrect. Serine is coded for by the codon AGU or AGC. Lysine is coded for by the codons AAA or AAG. Isoleucine is coded for by the codons AUA, AUC, or AUU.

Therefore, option C) asparagine is correct.

Answer:

Sugar, starch, and gluclose.

Explanation:

Answer:

Independent: amounts of oil

Dependent: amounts of popped kernels

Controlled variables: Kernel brand, cooking time, popping time

Explanation:

Independent variables are what are changed in the experiment. The dependent variables depend on the independent so they are what is affected each time. Usually this is what is being tested for. Controlled variables are those that aren't being tested and are kept the same each time to make sure it doesn't change the outcome.

Answer and explanation:

An ecosystem that is highly resilient is one that has the capacity to resist subjected damage by maintaining its normal patterns of biomass production and the cycling of nutrients. This damage can be anything from fires to deforestation.

A highly resilient ecosystem can be expected to adapt well to change, sometimes permanently, to survive indefinitely. For an ecosystem to be resilient, it has to be flexible and be able to adjust to uncertainty. Highly resilient ecosystems tend to have reproductive cycles, trophic cascades, and population connectivity - all of these characteristics give these ecosystems better chances of surviving different types of disturbances.

Answer:No

Explanation:I believe it is no due to the fact that the variable is being manipulated in all groups and in order to be a control groups the variable must remain the same or must not be manipulated.

hope this helps :)

Answer:

The correct answer would be - True.

Explanation:

In several organisms have structures, has no apparent role in the particular species and are residual parts from a past ancestor, but these structures were fully functional in the ancestors of the species. These structures are called vestigial structures or organs.

The example of such structures are, wings of the flightless birds, appendix of human and many other, all these structures has no function in the body of the individuals of the particular species but is fully functional in ancestors.

Thus, the correct answer is - true.

Answer:

Unity is the other name of cohesion.

Explanation:

The property of cohesion is to sticking together of something. The molecules of liquid stick together with the help of cohesion. This cohesion property  is very important for plants because with the help of this property, plants take water through roots from the soil and the water molecules are stick together with the help of cohesion. If cohesion is not present then the uptake of water can not be possible.

The pancreas is an organ directly associated with the digestive and Endocrine systems.

A intricate system of glands and organs makes up the endocrine system. Your body's metabolism, energy level, reproduction, growth and development, and response to injury, stress, and mood are all regulated and coordinated by hormones.

The endocrine system is made up of the following components:

The optic chiasm, where the optic nerves behind each eye intersect, and the hypothalamus are both found at the base of the brain. In the center of the brain, beneath the corpus callosum, is where you'll find the pineal body.

cell b is eukaryotic because it has a nucleus

Answer:

the answer is B. the amount of available resources

Explanation:

The carrying capacity of an ecosystem determines the amount of available resources. Therefore, option B is correct.

The term ecosystem is defined as the community or group of living organisms that live together and interact with each other in an environment. The biotic and abiotic components are linked together through nutrient cycles and energy flows.

Ecosystem plays an important role to purify our air, maintain our soil, regulate the climate, to clean our water, recycle nutrients and provide us with food. They are at the foundation of all civilization and sustain our economies.

The carrying capacity of an ecosystem determines the amount of available resources. Carrying capacity depends on many abiotic and biotic factors in the ecosystem.

Thus, option B is correct.
