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.

Which is a benefit of binomial nomenclature?
1.Fewer common names
2.Increased understanding and communication
3.Reduced plant-related poisoning
4.Better understanding of genetics of plants

Answers

2) Increased understanding and communication.

Various cultures and societies shape individual names for a particular organism. However, binomial nomenclature breaks this barrier to allow the scientific community to communicate more efficiently.

For example, the panther or mountain lion can simply become Puma concolor — thus, eliminating confusion. I hope this helps.

In the plasma membrane, the phospholipid heads Group of answer choices are isotonic and do not respond to water. are hydrophobic and face inward, shielded from water. are hydrophilic and face inward, shielded from water. are hydrophilic and face outward toward the aqueous solution on both sides of the membrane. are hydrophobic and face outward toward the aqueous solution on both sides of the membrane.

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.

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.

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.

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.

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.

As more is learned about cancer, it has become clear that cancer, with few exceptions, ________. Group of answer choices is only dependent on the inherited genetics is a result of genetics and environmental factors is 100% dependent on inherited genetics has no genetic basis

Answers

Answer: Is a result of genetics and environmental factors.

Explanation:

Cancer is the common name for a group of diseases in which there is a division of the body's cells, whose growth exceeds that of normal tissues and which persists in the same excessive manner. It can begin in a localized manner and spread to other surrounding tissues and its malignancy is very variable, according to the aggressiveness of its cells and other biological characteristics of each type of tumor. In general, the behavior of cancer cells is characterized by lacking the reproductive control required by their original function, acquiring the capacity to invade tissues (metastasis), spreading through the organism via the lymphatic or circulatory system, and causing the growth of new tumors in other parts of the body.

A gene is a hereditary unit composed of DNA that carries the instructions for producing proteins, which do much of the work in our cells. Certain genetic alterations can cause cells to evade growth controls and become cancerous cells. These changes can be inherited from our parents if the changes are present in the germ cells (eggs and sperm) and they are called germline changes. In addition, cancer-causing genetic changes can also be acquired during a person's lifetime (somatic or acquired changes), as a result of DNA errors that occur when cells divide either spontaneously or by exposure to carcinogenic substances that damage DNA (environmental factors), such as certain chemicals in tobacco smoke, or radiation, such as ultraviolet rays from the sun. These substances damage DNA, acting as mutagens.

Sometimes, the changes are not in the DNA sequence. For example, the epigenetic modifications are the presence of chemical marks in DNA which can determine if the gene is expressed. This means, whether and how much messenger RNA is produced, because the messenger RNA is translated into proteins.

So, cancer cells have genetic changes compared to normal cells. These changes are due to mutations that can be inherited, acquired spontaneously during life, or acquired due to environmental factors such as sun exposure, smoking, and other factors. In addition, the fact that a person has the cancer-related mutation does not necessarily mean that he or she will develop the disease during his or her lifetime. In some cases, even if they have this genetic vulnerability, they remain healthy, because cancer is a multifactorial disease that depends on many factors, such as the immune system, nutrition and certainly many others currently unknown to medicine.

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.

Elephants are not the most common species in African grasslands. The grasslands contain scattered woody plants, but they are kept in check by the uprooting activities of elephants. Take away the elephants and the grasslands convert to forests or to shrublands. The newly growing forests support fewer species than the previous grassland. Given this, elephants can be defined as what type of species in this community

Answers

Answer:

The elephants are the keystone species in this ecosystem.

Explanation:

The elephants' job is to knock down trees from time to time to get food from tall stock. This prevents the trees from overpopulating and allows shrub lands to stay in place. This is important as herbivores can continue to graze in large herds and carnivores can continue using the same hunting strategies with little to no push backs by trees.

This makes to elephants a keystone species as without them, the foundation species will decrease in population and create a whole different ecosystem with the trees as the new foundation species.
