What's photosynthesis?

[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]

Photosynthesis is the process in which green plants derive their food (nutrients and water) through the capturing of light energy (sunlight) and using it to convert carbon dioxide (CO2) and water (H2O) into oxygen (O2) and other substances (compounds) that are rich in energy. Chlorophyll a green pigment present in plants is used in this process.

This organ stores the main metal ion that forms part
of the red blood cell. Which ion is this, and what
molecule is it a part of inside the red blood cell?

Answers

Answer:

a. Iron (Fe) ion

b. Haemoglobin

Explanation:

Red blood cells (RBC), also known as erythrocytes, are one of the cells found in the blood. Red blood cells are the major components of the blood involved with the transport of oxygen throughout the body. Red blood cells are able to do this because they contain proteinous molecules called HAEMOGLOBIN.

Haemoglobin is a molecule that contains hemic iron groups. Haemoglobin is composed of an IRON ION at the core of its structure, which binds to oxygen atom. Hence, according to this question, haemoglobin is a proteinous molecule that contains iron-binding heme groups in the red blood cells.

Harry is doing a research project on the movement of plants from the ocean to land. He leaned that plants evolved
vascular tissues, which enabled them to pull water from the ground and survive on land. Which is most likely
another adaptation that contributed to the success of land plants?

cell walls?
chloroplasts
waxy cuticle
gametes

Answers

Answer:

Waxy Cuticle

Explanation:

Waxy Cuticle retains water. It's the closest in terms of surviving on land. For instance, the plants living in water do not need waxy Cuticle to retain or maintain water. The plants on land requires waxy Cuticle because the temperature is hotter than in the water and they are at higher risk of loosing water during hot seasons and climate. waxy Cuticle aids in their water retention allowing them to adapt to live on land.

what is the prediction of the outcome.genetic crosses between various organisms

Answers

Answer:

The results of genetic crosses can be predicted using a chart called a Punnett square. In a Punnett square, the possible male and female gametes of each parent are written across the side and top of the square. The interior squares represent every possible combination of gametes that could combine to form a zygote.

Explanation:

To fill in the square, look at the alleles of the games on the outside edges and bring them across and down to fill in the center of the square. If the offspring is heterozygous, we will write the capital letter in front of the lower case letter.

In the example below T=tall plants and t= short.

The evolutionary history and development of whales has been hotly debated. Recently there has been a major shift in our understanding of the processes used to detail whale evolution. This indicates that: Group of answer choices A) Aspects of evolution are constantly being challenged and explored in light of new evidence. B) Gaps in the fossil records will never allow us to fully understand evolution. C) Scientists studying evolution typically present ideas with very little evidence, leaving it to others to find proof of their ideas. D) Much of the science of evolution is based on speculation that can easily be changed when scientists think of new ideas.

Answers

Answer:

Aspects of evolution are constantly being challenged and explored in light of new evidence

Explanation:

The whole idea of evolution has to do with the fact that organisms developed into their present form from simpler life forms. According to Oxford dictionary, evolution is; ''the process by which different kinds of living organism are believed to have developed from earlier forms during the history of the earth.''

Evolution depends on evidence from fossil records. Evidences that support the theory of evolution continue to be amassed as science advances. Hence, aspects of evolution are constantly being challenged and explored in light of new evidence.

For this reason, the evolutionary history and development of whales is being hotly debated and there has recently been a major shift in our understanding of the processes used to detail whale evolution.

Answers

Answer:

a,the ability to go from a single cell to multicellular organism

The existence of multiple nuclei in a supercell is the characteristic feature of the Plasmodial slime molds, hence option C is correct.

What are Plasmodial slime molds?

It is one large cell called a supercell surrounded by a single membrane without cell walls having multiple nuclei, commonly founds on decomposing forest litter and rotting wood.

This organism is found by the fusion of multiple flagellated cells and which makes the structure of supercells, its formation depends on the availability of food.

It glides along the way where the presence of food particles is observed generally bacteria, lifting and engulfing this food. It has a diameter of 3 to 4 centimeters.

Therefore, Plasmodial slime molds are characterized by the existence of multiple nuclei in a supercell.

Why do cells use fat and starch for long-term energy storage instead of ATP molecules?
O ATP is used for long-term storage, while fat and starch are used for immediate energy.
O ATP is used for short-term energy and to build molecules of starch and fat.
O Fat and starch are unstable and can be stored short-term, while ATP molecules are stable and stored long-term.
O Fat and starch are stable if used as energy immediately, while ATP is used as long-term storage.

Answers

The answer to your question is B :)

Answer:

Cells use fat and starch for long-term energy storage instead of ATP molecules because fat and starch are more efficient energy storage molecules than ATP.ATP is a molecule used for immediate energy, not for long-term energy storage.

Fat and starch are complex carbohydrates that can be broken down to release energy. Fat molecules are primarily composed of carbon and hydrogen, while starch is made of glucose molecules.Both fat and starch can be broken down through cellular respiration to produce ATP molecules that can be used to power various cellular processes.
However, because fat and starch molecules contain more chemical energy than ATP, they can provide a much larger amount of energy over a longer period of time.

Furthermore, ATP molecules are relatively unstable and cannot be stored for long periods of time, while fat and starch can be stored in specialized cellular structures for long-term energy needs.

Answer:
plankton and algae

Hope that help

The types of organisms that make up the majority of life on the surface of the pelagic zone are plankton and algae. That is the last option, as plankton and algae are the primary producers in the surface layer of the pelagic zone.

What are the zones of water?

The pelagic zone is the open ocean area that comprises the largest ecosystem on Earth. It is divided into different layers depending on the depth and amount of sunlight that penetrates the water. The surface layer of the pelagic zone, also known as the photic zone, is the layer that receives enough sunlight for photosynthesis to occur, and it is where most of the ocean's primary production takes place.

Hence, the types of organisms that make up the majority of life on the surface of the pelagic zone are plankton and algae, which is the last option.

Group of answer choices is located near the base of the superior mesenteric artery arises from the greater splanchnic nerve projects postganglionic fibers that innervate the small intestine and the kidney and urinary bladder arises from the lesser splanchnic nerve arises from the lumbar splanchnic nerve

Answers

Answer:

The correct answer is ''arises from the greater splanchnic nerve''

Explanation:

The greater splanchnic nerve or great adrenal nerve, originates in the thoracic sympathetic chain from vertebral levels T5 to T9 (T10). It runs over the bodies of the thoracic vertebrae and as it descends it becomes more anterior. It enters the abdomen crossing the diaphragmatic pillar and ends at the celiac plexus. The upper part of each celiac ganglion continues with the greater splanchnic nerve. The collateral or prevertebral ganglia innervate the abdominal and pelvic organs and viscera. The celiac ganglion receives preganglionic fibers from T5 to T12 and innervates the stomach, liver, pancreas, gallbladder, small intestine, spleen, and kidneys.

Answers

Answer:

hydrophilic and face outward toward the aqueous solution on both sides of the membrane

Explanation:

The cell membrane is mainly composed of phospholipids, which are arranged in a lipid bilayer. In general, phospholipids consist of a glycerol unit, a phosphate group, and two fatty acids. In a lipid bilayer, hydrophilic (polar) phosphate heads are always oriented outwards and interact with surrounding water molecules; whereas hydrophobic fatty acid tails are oriented towards the center of the lipid bilayer away from water. It is for that reason that phospholipids are considered to be amphipathic molecules, where fatty acids confer hydrophobic properties and polar phosphate groups confer hydrophilic properties.
