What makes it hard for an astronaut to breathe in space ?

Answers

Answer 1

they need a oxegen tank cause you can’t breathe in space there’s no air cause there’s no trees so it’s like scuba diving you can’t breathe with out a oxygen supply and it might be uncomfor table and even few 30 mins you have to get a new oxygen tank (sorry if I’m wrong :clownface: )

Known as the 'Pine Tree State; Maine's state tree is the Eastern white pine. Consider the model. Cärbon dioxide, water, and sunlight
are reactants of photosynthesis and are used to produce glucose and release water as a byproduct. What advantage does the pine tree
have in performing photosynthesis compared to deciduous trees such as oak or maple?
34)
A) Pine trees need less water to do photosynthesis.
B) Pine trees produce twice as much glucose as deciduous trees.
C) Pine trees do not lose their leaves and can photosynthesize all year.
D) Pine trees get more sunlight than oak trees due to their darker color.

Answers

Answer:

C) Pine trees do not lose their leaves and can photosynthesize all year.

Explanation:

In cold-temperate and Arctic regions, however, evergreens are typically cone-bearing shrubs or trees (conifers), such as pines and firs. Many tropical species of broad-leaved blooming plants are evergreen. Thus, option C is correct.

What are features of pine trees?

Pine trees may photosynthesize in the winter because they retain their needles all year long! Compared to trees that lose their leaves, this is a significant advantage.

Their leaves therefore stay green and stay attached for a longer period of time than their deciduous counterparts because they can preserve more water.

However, because of their tiny surface area, needles are not as effective at absorbing the sun's energy.

Therefore, Pine trees do not lose their leaves and can photosynthesize all year.

Answer:

Active Transport.

Explanation:

Moving substances across a cell membrane against their concentration gradient, from an area of lower concentration to a region of greater concentration, is a process known as active transport in cells.

Thus, Active transport uses external energy—typically in the form of ATP (adenosine triphosphate)—to move materials against the concentration gradient as opposed to passive transport, which depends on the natural movement of particles.

Active transport involves the movement of materials across the cell membrane by means of specific membrane proteins called carrier proteins or pumps.

Thus, Moving substances across a cell membrane against their concentration gradient, from an area of lower concentration to a region of greater concentration, is a process known as active transport in cells.

Proteins help Store energy and the genetic code. The long chain of amino acids describes the long chain of polypeptides.

What is protein?

Proteins are among the most prevalent organic molecules in biological systems and have a much wider range of structural and functional variations. Many thousands of proteins, each serving a different purpose, can be found in a single cell.

All proteins are composed of one or more chains of amino acids, despite the fact that their structures and activities differ substantially from one another.

In biological reactions, enzymes function as catalysts, accelerating the reactions. Each enzyme may distinguish between one or more substrates, or the molecules that act as the catalysts for the reactions they catalyze.

Therefore, Proteins help Store energy and the genetic code. The long chain of amino acids describes the long chain of polypeptides.

what forms after the glycosidic linkage reaction between glucose and galactose is complete

Answers

What forms after the glycosidic linkage reaction between glucose and galactose is complete would be lactose.

Glucose and galactose are known as simple sugars or monosaccharides. Monosaccharides can combine together to form disaccharides or even polysaccharides.The combination of monosaccharides to form di or polysaccharides happens by a process known as condensation reaction.The condensation reaction results in the formation of glycosidic linkage or bond and elimination of water moleculesGlycosidic bond is a type of covalent bond th joins one sugar molecule to another sugar or non sugar molecule.

Thus, lactose is a dissacharide consisting of one glucose and one galactose unit which combine together by condensation and formation of glycosidic bond with elimination of water.

how does your body acquire the oxygen the cells in your body need to function?

Answer:

You take in oxygen and it goes to your lungs. It spreads through your body, going through your bloodstream, and going to your heart. The excess oxygen turns into carbon dioxide leaves through your mouth. When it leaves, the plants take the carbon dioxide and turn it back into oxygen, and repeating this process.

Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.

What are the functions of hemoglobin?

Hemoglobin is a protein in your red blood cells that carries oxygen to your body's organs and tissues and transports carbon dioxide from your organs and tissues back to your lungs.

Hemoglobin, abbreviated Hb or Hgb, is the iron-containing oxygen-transport metalloprotein present in red blood cells of almost all vertebrates as well as the tissues of some invertebrates. Hemoglobin in blood carries oxygen from the respiratory organs to the rest of the body.

Hemoglobin is essential for transferring oxygen in your blood from the lungs to the tissues. Myoglobin, in muscle cells, accepts, stores, transports and releases oxygen.
