A student claims that the only difference between prokaryotic cells and eukaryotic cells is that
eukaryotic cells have a nucleus, but prokaryotic cells do not. What is wrong with this claim?

The description of the cell types is incorrect.

Prokaryotic cells have a nucleus, and eukaryotic cells do not.

The description of the cell types is incorrect. Both prokaryotic and eukaryotic cells have a nucleus.

There is another difference between the cell types. Eukaryotic cells have membrane-bound organelles, but
prokaryotic cells do not.

There is another difference between the cell types. Eukaryotic cells have a cell membrane, but prokaryotic
cells have a cell wall instead.

Answer:

below pH 7 H+ is greater because hydrogen ions are produced only by acids in an aqueous solution and acids have a pH below 7

bases have a pH that is greater than 7.

Answer:

B. 48 degrees c

Explanation:

Answer:

48 Degrees Celsius

Explanation:

It’s going up by one more than it went up the last time. Another way of looking at it is the increasing factor of the degrees is being added by one every single 2 hours.

Answer:

Abductor Muscle.

Explanation:

The tensor fasciae latae works in synergy with the gluteus medius and gluteus minimus muscles to abduct and medially rotate the femur. The TFL is a hip abductor muscle. To stretch the tensor fasciae latae, the knee may be brought medially across the body (adducted).

Hope this helps!! Brainliest?? Anyways have a great day!! :))

Answer:

Usually the Y chromosome. It is recessive because if one Y chromosone is mutated with red-green colorblindness and the X is not, the child will have colorblindness. But, if one X chromosome has the mutation and the other X does not, they will cancel out, meaning the child will not have colorblindness.

Answer:

Nucleus.

Explanation: The nucleus is the brain of the organelle. It controls most of its functions and also holds the DNA for that cell.

Answer:

In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

Explanation:

so the relationship between.

Answer:   Chromosomes > DNA > Genes

Chromosomes are thread-like structures of DNA coiled around proteins. Genes are specific portions of DNA that code for the production of proteins that are used and/or expressed by a body.

Answer:

I think it would be #3, Beaks got longer because the only birds that survived had larger beaks that could crack the hard seeds

Explanation:

In years of extreme drought, the small, delicate seeds get eaten up quickly, leaving behind only the largest, toughest seeds.

Answer:

Hi

Explanation:

“Sensory cues influence homeostasis by modulating hormone secretion. ... In step 1, sensory cues change the activity of sensory neurons. In step 2, the sensory information is processed and transmitted, which leads to step 3, where neuro- or nonneuronal endocrine cells secrete hormones required in maintaining homeostasis.”

False. The purpose of the endosperm is to provide nutrients for the embryo.

Answer: S

Explanation: In the eukaryotic cell cycle, chromosome duplication occurs during "S phase" (the phase of DNA synthesis) and chromosome segregation occurs during "M phase" (the mitosis phase).

Answer:

4. half of a duplicated chromosome

Explanation:

in mitosis,when a cell splits its called a sister chromatid

Answer:The answer is b. Pioneer species

Step-by-step explanation; The first species to colonize an area after a major disturbance are called pioneer species; they help to form the new environment. Secondary succession occurs after a disturbance such as a forest fire, where there is still some organic matter to allow new plants to grow.

Answer:In Protostomes (“mouth first”), the mouth develops at the blastopore (Figure 3). In Deuterostomes (“mouth second”), the mouth develops at the other end of the gut (Figure 3) and the anus develops at the site of the blastopore. Protostomes include arthropods, mollusks, and annelids.

Explanation:

The ability to feel pain in the left arm is most likely controlled by the RIGHT PARIETAL LOBE. It is one of the lobes of the brain.

The parietal lobes of the brain are located behind the frontal lobe at the top of the brain.

The right parietal lobe is a part of the brain involved in non-verbal memory and mathematical reasoning.

The primary motor cortex on the right region of the brain controls the movements of the left side of the body and vice-versa.

Collagen has: A. pyrrolidine rings, which stabilize helices and glycine residues at every third position (because only glycine residues can fit inside of the super-helical cable).

Collagen can be defined as the main or most abundant structural protein found in the bones, tendons, connective tissues, skin and muscles of a living organism such as a human being.

Basically, collagen is a chemical substance (protein) made up of amino-acids and it holds the human body together.

Hence, collagen typically makes up about 30% of the proteins contained within the human body.

Additionally, collagen comprises the following specific amino-acids:

Each of the three chains of a collagen triple helix with 3.3 residues per turn, is normally stabilized by the steric repulsion between the pyrrolidine rings of hydroxyproline, glycine and proline residues.

Therefore, the pyrrolidine rings of collagen helps in the stabilization of helices and glycine residues, at every third position because the only residue that fits inside of the super-helical cable is the glycine residues.

Answer:

WHAT DRIVES SURFACE CURRENTS?

Surface currents in the ocean are driven by global wind systems that are fueled by energy from the sun. Patterns of surface currents are determined by wind direction, Coriolis forces from the Earth's rotation, and the position of landforms that interact with the currents.

DIFFERENCES IN AIR TEMPERATURE.

Movement of air due to differences in temperature between two locations is known as convection or advection. Convection is the term commonly applied to vertical movement of air, whilst advection is used in the context of horizontal displacement of air.

DIFFERENCES IN CLIMATE.

Weather refers to short term atmospheric conditions while climate is the weather of a specific region averaged over a long period of time. Climate change refers to long-term changes.

DIFFERENCES IN WATER DENSITY.

High temperature makes water less dense. As water gets warmer, its molecules spread out, so it becomes less dense. As it gets colder, it becomes denser. Most chemicals get denser when they turn from a liquid to a solid, but water is different.

DIFFERENCES IN WATER SALINITY.

As we have seen, most differences in salinity are due to variations in evaporation, precipitation, runoff, and ice cover. All of these process occur at the ocean surface, not at depth, so the most pronounced differences in salinity should be found in surface waters.

Explanation:

Relaxation occurs when stimulation of the nerve stops. Calcium is then pumped back into the sarcoplasmic reticulum breaking the link between actin and myosin. Actin and myosin return to their unbound state causing the muscle to relax.

The number that represents DNA synthesis in the figure would be II.

DNA synthesis happens at the S phase in the interphase of the cell cycle, just after the G1 or cell growth phase and before the G2 or protein synthesis phase.

During the S phase, the amount of DNA in the cell doubles as replication of DNA takes place. However, the number of chromosomes remains constant.

The doubling of the amount of DNA is responsible for the sharp rise in the line that represents the amount of DNA in the figure. Thus, the region of a steep rise in the amount of DNA would represent the DNA synthesis phase.

Explanation:

Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
