Gymnosperms are a group of higher plants that produce naked seeds i.e. seeds not cased by a fruit. Pteridophytes are a group of lower plants that have vascular bundles.

WHY ARE GYMNOSPERMS ADVANCED THAN PTERIDOPHYTES?

Gymnosperms bear seeds while pteridophytes bear spores (seedless)Gymnosperms do not require water for fertilization to occur while pteridophytes require water for their fertilizationGymnosperms have a well developed root system while pteridophytes do not have a well developed root system (they use rhizoids)Gymnosperms exhibit secondary growth while pteridophytes do notGymnosperms undergo pollination while pteridophytes do not.

The sodium-potassium pump does not do which of the following actions?
-Moves sodium molecules against their concentration gradient into the cell
using ATP.
-Moves sodium molecules against their concentration gradient out of the cell
using ATP.
-Maintains the cell's physiological needs by establishing an electrochemical
gradient.
-Moves potassium molecules against their concentration gradient into the cell
using ATP.

Answers

The sodium-potassium pump does not allow the movement of sodium molecules against their concentration gradient into the cell  with the use of ATP molecules.

In sodium-potassium pump, the sodium moves outside the cell whereas potassium moves inside the cell with the help of using ATP molecules. The sodium-potassium pump maintains the gradient of higher concentration of sodium extracellularly means outside the cell and a higher level of potassium intracellularly means inside the cell. This process is done only in the presence of ATP molecules that provides a force for the movement of sodium and potassium so we can conclude that no movement of sodium occur inside the cell in the sodium-potassium pump.

https://brainly.com/question/24347696

Answer: Moves sodium molecules against their concentration gradient INTO the cell using ATP.

Explanation:

The sodium-potassium pump moves sodium molecules against their concentration gradient out of the cell and moves potassium molecules against their concentration gradient into the cell. It also helps to regulate internal physiological needs through gradients. However, it doesn’t move sodium ions into the cell—that occurs through passive transport.

Answer:

Pneumotaxic centre in the pons region of the brain can moderate functions of the respiratory rhythm centre.

Answers

Answer:

Reducing the intensity of runoff.

Explanation:

Terrace farming prevent landslides and erosion to occur by reducing the intensity of runoff. This farming also reduce the risk of drought due to raising the moisture content in the soil and allowing water to slowly infiltrate into the soil. Due to terrace farming, the runoff water moves very slowly which causes less erosion of the soil as well as reduces the intensity of water flow which causes more infiltration.

Which of the following shows the correct energy flow during aerobic respiration?
A. Lipids, Glucose, ATP, cells
B. ATP, Glucose, cells
C. Carbohydrates, Glucose, ATP, cells
D. Carbohydrates, Glucose, Lactic acid, ATP

Answers

The correct energy flow during aerobic respiration is ATP, Glucose, and cells. Thus, the correct option is B.

What is Aerobic respiration?

Aerobic respiration may be defined as the process of conversion of glucose into carbon dioxide, water, and energy via the intermediate product of pyruvate in presence of air.

The release of energy in aerobic respiration is found to be greater as compared to anaerobic respiration.

This released energy is immediately used to synthesize a molecule called ATP via glucose that fuels the cells for metabolic activities.

Therefore, the correct option for this question is B.

The CT reveals several issues with the cranial structure, one of which might be in the cribriform plate but the image isn't well defined. What non-invasive test can you do to test if the cribriform plate is severely damaged? Why?

Answers

The non-invasive test that can be used to test if the cribriform plate is severely damaged is called the pledget study.

CRIBRIFORM PLATE is the part of the ethmoid bone that forms the nasal cavity.

The olfactory nerve which is part of the cranial nerves passes through the small opening found in the cribriform plate.

A damage to the cribriform plate leads to cerebrospinal fluid (CSF) leak which usually comes out from the nose and ears.

Therefore to test if the cribriform plate is severely damaged, the pledget study is performed.

Pledget study is a non-invasive method of diagnosing a CSF leak.

To perform this test,

Cotton pads called Pledgets are placed in the nostrils.If the leaking fluid contains CSF it will be detected.

The presence of CSF shows that there is damage to the cribriform plate.

This method is non invasive because it doesn't require the breaking or opening of any part of the body.
