Answer: The Answer is D, Insects.

Explanation: If you look on the chart, you can see insects are the furthest away, indicating they are the least similar.

Answer: Insects.

Explanation:

They lack an internal skeleton, lay eggs, and share the least amount of similarities.

Answer: Basalt

Explanation:

Basalt is a dark igneous rock that usually forms from lava flow. It is the most common rock at the bottom of the Earth's oceans where it underlines most basins which means that it, by extension, is the largest type of rock underlying the Earth's surface.

Basalt is phaneritic-rock as it forms from lava that has crystallized on or close to the Earth's surface and is made up of about 30% calcium-rich plagioclase feldspar, about  55% pyroxene, and about 15% olivine.

Answer:

AUG AUC CAA AGU GGG UAA

Amino Acids:

Methionine, Isoleucine, glutamine, Serine, Glycine, Stop codon

Explanation:

DNA converted to mRNA goes like this

Apples Under Trees

Cars in Garages

now let me explain this,

A(Adenine) goes with T(Thymine)

C(Cytosine) goes with G(Guanine)

BUT,

this is where the U in under takes place since we are transcripting, there is no T, it is replaced with U(Uracil)

Ex: CAT

Would be

GUA

C is paired with G, A is paired with U in transcription, and T is paired with A.

Ex: AGG

Would be

UCC

A is with U in transcription, G is paired with C.

Now we find the amino acids aka traits :)

I like to use a circle codon mRNA chart

Methionine, Isoleucine, glutamine, Serine, Glycine, Stop codon

(can go in depth about codons and stuff, or the codon chart if you don't know how to use either the box or circle one)

Explanation:

Answer:

its a on ed

Explanation:

The observation that most likely led to Jenna’s conclusion is a change of odor. Thus, the correct option is A.

Chemical changes may be defined as those changes through which one chemical substance gets transformed into another chemical substance. This occurs in a variety of steps and types.

A difference in the smell of leftover mashed potatoes indicates the change in odor which is observed by Jenna.

A decrease in temperature, a change in moisture, and a decrease in mass do not make any sense with respect to difference in smell.

Therefore, the observation that most likely led to Jenna’s conclusion is a change of odor. Thus, the correct option is A.

Answer:

In order for polar compounds to enter into the hydrophobic space of phospholipid tails, it would need to break the many hydrogen bonds

Explanation:

In the presence of water, the hydrophobic tails tend to interact with each other, creating a hydrophobic space from which water is excluded and in which other hydrophobic molecules can be trapped, while the polar head interacts with water, and is solvated, preserving the hydrophobic part from all contact with water. For a hydrogen bridge to form, a molecule that has hydrogen attached to an atom of high electronegativity and another molecule that has another electronegative atom with high electron density (that is, a negative partial charge) is required. Water molecules in the bulk of the body of water maintain multiple interactions with other molecules through an extensive network of hydrogen bridges, so for polar compounds to enter, it would be necessary to break many of these bonds.

Answer:

No

Explanation:

No, plants do not take in air with their roots. Roots are designed to absorb water and minerals from the soil. In order to get the air and carbon dioxide they need for photosynthesis, plants have specialized structures called stomata in their leaves and stems that allow air to enter and exit. These stomata regulate the movement of gases into and out of the plant, so the plant can take in the carbon dioxide it needs and release the oxygen it produces.

Answer:

What are the statements?

Explanation:

...

Answer:

The skeletal muscles connect to the bones and work with connective tissue at the joints to allow for movement. The muscles connect to the nervous system and allow initiation of movement through nerve signals to and from the brain. The bones and muscles are supported by connective tissue, which plays an integral role in structural support.

The first statement "Consider a favorable reduction-oxidation (redox) reaction: the reactant that is reduced will have a less positive reduction potential."

The reduction potential is the tendency of a molecule to gain electrons and get reducted. Larger positive values of reduction potential (measures in millivolts) indicate a greater tendency of the molecule to get reduced, and the smaller the value of reduction potential, the less likely it is for the molecule to get reducted.

For the redox reaction, the reactant that is reduced will have a less positive potential reduction, this happens because the molecule is already reduced, so the statement is TRUE.

Second statement "Phosphocreatine is an energy storage molecule that can be used to regenerate NAD+ for muscle contraction."

Phosphocreatine is a substance found in the muscle tissue of vertebrates. Its function is to maintain the pH of the environment within the muscle fiber and recycle ADP into ATP for muscular activity. The reaction in which the Phosphocreatine gives a Phosphate to ADP to create ATP is possible thanks to the action of the enzyme Creatin Kinase as follows:

The second statement is therefore FALSE since the Phosphocreatine is used to recycle ATP and not NAD+

The pairing of complementary strands of DNA due to hydrogen bonding is called semi-conservative replication.

The biological process of creating two identical copies of DNA from a single original DNA molecule is known as DNA replication.  All living things replicate their DNA, which is the primary mechanism for biological inheritance. This is necessary for:

A double helix (two linear strands that run counterclockwise and twist together) of two complementary strands makes up DNA.

These strands are split apart in the replication process. The mechanism of semiconservative replication uses each strand of the original DNA molecule as a template to create its counterpart. The new helix will be made up of an original DNA strand as well as a freshly synthesized strand as a result of semi-conservative replication.

Answer:

All food chains start with energy from the sun. This energy is captured by plants. Thus the living part of a food chain always starts with plant life and ends with an animal. Plants are called producers because they are able to use light energy from the sun to produce food (sugar) from carbon dioxide and water.

Explanation:

From the diagram, circuit a and b are series circuit while c is parallel. Option C

The components in a parallel circuit are linked together so that the electric current can go along several different routes. The power source is directly connected to each component, forming parallel branches. While the current in a parallel circuit can vary, the voltage between each component is constant.

The components of a series circuit are connected one after the other to create a single path for the passage of electricity. While the voltage across each component can change, the current flowing through each component is constant.

Trophic level in ecology is the particular position occupied by a group of organisms in a food chain.

A food chain is the feeding relationships between species in a biotic community. In the food chain, living organisms derive energy from one another by feeding on one another.

Passive transport .

Explanation:

Passive transport is a kind of transport which is used by Paramecium to remove excess water from its cytoplasm. There is a inverse relationship between the contractile vacuole activity and the environmental salt concentration because if there is salty environment, the contractile vacuole did not their function because there is difference in pressure and the water moves outside when there is salty environment. Bursting of paramecium occur if a biological toxin blocked the activity of the contractile vacuole because no excess water moves to outside environment.
