When the cell is removing and or excreting sodium from within the cell, against the natural tendency of matter, it is performing a type of active transport, called exocytosis, I believe. The sodium ions become associated with membrane enclosed structures called vacuoles, from the Golgi apparatus and later merge with the cell membrane of the cell to dispose the sodium carried within the vacuoles.

Which of the following blood vessels uses elasticity to push blood further along the bloodstream?

Arteries
Capillaries
Varicose veins
Atrioventricular node

Answers

The answer is Arteries 

Arteries carry oxygen-rich blood from the heart to capillaries. On the contrary, veins carry blood without oxygen from the capillaries to the heart. 
Arteries are very flexible and yet strong blood vessels so that efficient transport of oxygen-rich blood along the bloodstream through the organism is enabled.

1)carbohydrates
2)lipids
3)nucleic acids
4)proteins

Answers

3) Nucleic acid contains the genetic code.

Hope this helps!

Nucleic acids are the carriers of the genetic code. The molecules that carry and transmit genetic information in living things are called nucleic acids, specifically the deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) families. Therefore, the correct option is C.

The fundamental genetic material, DNA, is located in the nucleus of cells, while RNA is involved in gene expression and protein synthesis. Sequences of nucleotides, the constituent parts of nucleic acids, contain the genetic code. Proteins, lipids, and carbohydrates all play important roles in many cellular processes and functions within an organism, but none of them directly contain the genetic code.

Therefore, the correct option is C.

What is the main source of energy that drives the water cycle?

Answers

The sun is the main source of energy.
Final answer:

The sun is the primary source of energy that drives the water cycle. It provides the heat necessary for evaporation, the initial phase of the water cycle, and influences all subsequent stages of the cycle including condensation, precipitation, and surface runoff.

Explanation:

The main source of energy that drives the water cycle is the Sun. The sun's energy warms the oceans and other surface waters, which leads to the evaporation or sublimation of liquid or frozen water into the atmosphere. This water vapor then condenses into clouds, leading to precipitation that brings the water back to Earth's surface again, completing the water cycle.

Evaporation and sublimation are critical first steps in the water cycle. These processes involve the transformation of liquid water or ice into water vapor due to the Sun’s heat.

The water, now in a gaseous state, ascends into the atmosphere where it eventually condenses to form clouds due to lower temperatures at higher altitudes. This is referred to as condensation and it's often followed by precipitation, the process where water is returned to the Earth’s surface as rain, sleet, hail, or snow.

Upon reaching the surface, the water can take several paths. It can flow on the surface, leading to surface runoff, or it can seep into the soil contributing to subsurface water flow. Some of the water ends up in rivers and streams, referred to as streamflow, and eventually makes its way back to the ocean again, completing the cycle.

There are many methods used to obtain energy for use in our daily lives. Some of these methods have possible environmental consequences to rivers, groundwater, and organisms. One type of pollution involves excess carbon dioxide being released into the air. Some of the carbon dioxide reacts with water to form acid rain. Which energy sources can release carbon dioxide and carbon monoxide waste into the atmosphere?

Answers

Answer: Coal,petroleum

Explanation:

he process that we call "burning" actually is chemical reactions with oxygen in the air. For the most part, the carbon combines with oxygen to form carbon dioxide (CO2), and the hydrogen combines with oxygen to form water vapor (H20).

Some  of the carbon dioxide reacts with water to form acid rain, and the energy sources can release carbon dioxide and carbon monoxide waste into the atmosphere through the burning of fossil fuels, coal, oil, etc.

What is the significance of burning fossil fuels?

Carbon dioxide, which is also considered a "greenhouse gas," and other greenhouse gases in the atmosphere trap heat from the sun but never let the heat pass through the earth's atmosphere and make the earth hot. This is caused by the combustion of fossil fuels and causes air pollution, which can be harmful to human health and the earth.

Hence, some of the carbon dioxide reacts with water to form acid rain, and the energy sources can release carbon dioxide and carbon monoxide waste into the atmosphere through the burning of fossil fuels, coal, oil, etc.

Explanation:

The correct order of cellular respiration is Glycolysis > Krebs cycle > electron transport chain, hence option C is correct.

What is cellular respiration?

It is the cellular process through which cells get oxygen inside it and release carbon dioxide outside of it.

Cellular respiration is the metabolic process that starts with the degradation of metabolic products and ends with the complete oxidation of these products.

Glucose is oxidized via glycolysis and produces pyruvate as an end product of glycolysis, this pyruvate is further oxidized into the Krebs cycle and releases electrons for the synthesis of ATP.

Therefore, for correct order of cellular respiration inside the cell option C, Glycolysis, Krebs cycle, electron transport chain is correct.

Select the FALSE statement below about the structure of myoglobin.

a. The O2-binding pocket of myoglobin contains several nonpolar amino acid sidechains that can interact favorably with a nonpolar molecule of O2.

b. The polypeptide of myoglobin provides a pocket for O2 to fit, and stabilizes the bound O2 via hydrogen bonding with the distal His.

c. The polypeptide of myoglobin protects the heme iron from oxidation.

d. The active site of deoxy myoglobin is 5-coordinate with a histidine occupying one axial position while the other axial position is left open for oxygen binding.

e. Myoglobin has a single polypeptide chain so it has 1o, 2o, 3o and 4o structure.

Answers

The answer is e. Myoglobin has a single polypeptide chain so it has 1o, 2o, 3o and 4o structure.

Myoglobin is an iron and an oxygen binding protein. It has a single polypeptide chain. Proteins with the single polypeptide chain cannot have quaternary (4o) structure. 4o structure of proteins includes an arrangement of multiple folded polypeptide chains (subunits) in a multi-subunit complex. Therefore myoglobin cannot have 4o structure as the single chain polypeptide. All other choices are correct.

Which of the following statements about seafloor spreading is false?

A. Continents move as the seafloor spreads along a mid-ocean ridge.
B. The oldest crust is closest to the mid-ocean ridge.
C. Magma rises through the mid-ocean ridge, forming basalt.

Answers

B. The oldest crust is closest to the mid-ocean ridge.
Answer;

B. The oldest crust is closest to the mid-ocean ridge.

Explanation;Seafloor spreading refers to the process by which new oceanic crust forms along a mid-ocean ridge and older oceanic crust moves away from the ridge. Seafloor spreading occurs at the mid-oceanic ridge where the divergent boundaries cause two plates to move away from each other resulting to the spreading of the sea floor.As the divergent plates move apart, new materials wells up and then cools at the edge of the plates. Seafloor spreading is important as it helps explain the continental drift in support of the theory of plate tectonics.
