Answer:

Sensory nervous system detects and encodes stimuli and then sends signals from receptors. (evidence below for a clearer answer)

Explanation:

"As a whole, the sensory nervous system detects and encodes stimuli and then sends signals from receptors, that is, sense organs or simple sensory nerve endings, to the central nervous system, that is, it transduces environmental signals into electrical signals that are propagated along nerve fibers."

Answer:

Use more than one termite and run many trials.

Explanation:

it's not A because we're not trying to figure out pencil's but the chemical's in ink. It's not B because using just one bug wouldn't really get us anywhere. It's not D because you'd actually want to try different brands of ink to see if maybe you had a lesser chemical ratio. It's C because not all the bugs will react in the same way as just one would. Also, doing multiple trials would show us if they would change their behaviors.

Answer:

no

Explanation:

no

Answer:

C. 40 Newtons

Explanation:

We are given the equation to calculate force:

Force=mass×accelleration

To find the answer, we just need to plug the given mass and acceleration into the equation. The units of these values are typically kg and m/s^2 when calculating the force in Newtons, which they already are (so we don't need to do any conversion).

Mass=10kg

Acceleration=4 m/s^2

F=ma

F=10×4

F=40 N

Therefore, the force of the object is 40 Newtons.

Answer:

Normal Function. The CFTR gene provides instructions for making a protein called the cystic fibrosis transmembrane conductance regulator. This protein functions as a channel across the membrane of cells that produce mucus, sweat, saliva, tears, and digestive enzymes.

Answer:

the exhalation of water vapor through the stomata.

Explanation:

Answer:

the release of water from plant leaves

Explanation:

Answer:

Secondary active transport by a symporter

Secondary active transport includes uphill transport of one substance against its concentration gradient coupled with downhill transport of another substrate. Glucose is transported against the concentration gradient into the cytoplasm and this active transport is driven by downhill transport of Na+ into the cells. This makes the transport of glucose a secondary active transport. Both glucose and Na+ are transported into the cell (in the same direction). Since both are moved simultaneously in the same direction, it is a symport.

Explanation:

Answer:

Primary osmosis diffusion

Explanation:

That is because intestinal cells give glucose to concentrional cells by transporting coca colas from walmart to ikea.

Answer: In biology, coevolution occurs when two or more species reciprocally affect each other's evolution through the process of natural selection. The term sometimes is used for two traits in the same species affecting each other's evolution, as well as gene-culture coevolution.

Explanation:

Answer:

If it decays by alpha decay, it will become an atom with 2 fewer protons and 2 fewer neutrons than the original atom. If the atom decays by beta minus (electron) decay, it will become an atom with one less neutron and one more proton than the original atom.

Answer:

they are second messenger molecules capable of triggering different signaling pathways

Explanation:

Second messenger molecules are intracellular signaling molecules that trigger different cellular responses. Examples of second messengers include Calcium ions (Ca2+), Inositol trisphosphate (IP3), and cyclic AMP (cAMP). Secondary messengers may be activated by different cellular responses, for example, cyclases that synthesize cAMP or by opening calcium ion (Ca2+) channels. For example, cAMP signaling is able to activate kinase enzymes that perform phosphorylation and interact with other effector molecules to mediate different biological functions (for example, regulation of glycogen and sugar metabolism). On the other hand, Ca2+ signaling is required for muscle contraction, neurotransmitter release, etc. Ca2+ signaling is known to exert allosteric control over enzymes and other types of proteins.

Answer:

Explanation:

The answers to your questions about genetic recombination are:

Independent assortment happens during metaphase I.

Fertilization happens during sexual reproduction.

Independent assortment is random chromosome alignment resulting in variation.

Crossing over happens during prophase I.

Fertilization fuses gametes to form offspring with genes from each parent.

Crossing over is the exchange of genetic information between non-sister chromatids.

Cerebrospinal fluid fills the ventricles of the brain and the space between the pia mater and the arachnoid.

Explanation:

Answer:

one will become very hard

the other one will kam wet

Answer:

Dominant is relating to or denoting heritable characteristics which are controlled by genes that are expressed in offspring even when inherited from only one parent. Recessive is relating to or denoting heritable characteristics controlled by genes that are expressed in offspring only when inherited from both parents, i.e., when not masked by a dominant characteristic inherited from one parent

here are the structures i hope it helps

Answer:

primary, secondary, tertiary, and quaternary.

Explanation:

four levels of protein

1. primary structure of a protein: this is the number and sequence of amino acids held together by the peptide bond in a polypeptide chain.

2. secondary structure of a protein: this described the interaction of the sequence of amino acids in a polypeptide chain, and the bond formed is hydrogen bond.

3. tertiary structure of a protein this is a 3 dimension structure of a protein in the polypeptide chain and the bond formed are hydrogen bond, ionic bond and disulfide bond.

4. quartenary structure of a protein this is a combination of more than one structure which is primary structure, secondary structure and tertiary structure. bond formed are disulfide bond and so on.
