I NEED HELP ASAP Sensors on a spider's legs feel the vibrations of a trapped insect and relay the information to the spider's brain through nerve electrical signals. For nerve cells to maintain these electrical potentials, sodium must be removed from the cell and potassium must be moved into the cell. Describe why this process is a form of active transport and what is required for active transport to occur?

Answers

Answer:

Please find the explanation below

- Energy (ATP) is needed for active transport to occur

Explanation:

According to this question, sensor's on a spider's legs relay information via nerve electrical signals to the brain when the vibrations of a trapped insect is felt. However, for nerve cells to maintain this electric potential, ACTIVE TRANSPORT must be carried out by removing sodium from the cell and potassium must be moved into the cell.

This is a form of ACTIVE TRANSPORT because pottasium ions are moved into the cell against concentration gradient i.e. from a region where it is in low concentration to where it is in high concentration. This active transport process is usually accompanied by the use of energy in form of ATP.

Which structures are highlighted? Which structures are highlighted? goblet cells submucosa chondrocytes in lacunae seromucous glands

Answers

The image is not given in the question, so the appropriate image is attached below:

Answer:

goblet cells

Explanation:

Goblet cells are the mucin-secreting glands found within epithelia. Their shape and size look like a goblet, hence named goblet cells, and contain narrow bases and wide apex.

The structure highlighted in goblet cells scattered within epithelia. Goblet cells function for producing mucin, create a protective mucus layer and immunoregulation.

Hence, the correct answer is "goblet cells".

Cane toads are large, nonnative, poisonous toads in Australia. After cane
toads entered Australia, scientists observed that the average head size in a
population of toad-eating snakes was getting smaller. Snakes with smaller
heads are not able to eat the large cane toads. What type of situation is this?
O A. Disruptive selection
B. Species richness
C. Directional selection
D. Genetic variation

Answers

The answer you are looking for is C

Natural selection is a process by which the organisms adjust to the variation in the environmental conditions so they can endure and thrive in the altered conditions.

The correct answer is:

Option C. Directional selection

This can be explained as:

Directional selection is a negative form of natural selection in which the inhabitants of one species is favoured over another.

The species with better trait characteristics will be favoured over the organism with less preferred attributes.

The allele recurrence in directional assortment shifts over time.

Therefore, toads with better traits (head size) are favoured over snakes with smaller mouth sizes.

scientists determined that organisms of the genus spinoloricus we eukaryotes and not prokaryotes because spinoloricus cells have --
A. flagella
B. hereditary material
C. Cell walls
D. Nuclear Membranes

Answers

C is correct: cell walls

Scientists determined that organisms of the genus spinoloricus we eukaryotes and not prokaryotes because spinoloricus cells have cell walls. Thus, option C is correct.

What are the difference between eukaryotes and prokaryotes?

Eukaryotes are distinguished from prokaryotes in that they organelles enclosed within a nuclear membrane. The organisms of spinoloricus are radically different from other known eukaryones in that they lack mitochondria and are able to exist in the absence of oxygen. However, their genetic material is contained within a nuclear membrane and they are therefore eukaryotes rather than prokaryotes.

Taking into consideration the main characteristic of each group, prokaryote, and eukaryote. In the first case, we have that it laks nucleus and has no sexual reproduction, meanwhile, the eukaryote has organelles and has sexual reproduction. Taking this into account we can proceed to answer each part.

Therefore, Scientists determined that organisms of the genus spinoloricus we eukaryotes and not prokaryotes because spinoloricus cells have cell walls. Thus, option C is correct.
