Are there any parts of the human body that get oxygen directly from the air and not from the blood?
Answer:
Yes. Upper-layer skin cells and the cells in the front surface of the eyes get a significant amount of oxygen directly from the air rather than from the blood. Human bodies have a huge demand for oxygen. As a result, the oxygen that is able to passively diffuse into the body directly from the air is not nearly enough to run the whole body.
Explanation:
Suggest THREE uses that the leaf cells can make of the glucose produced in photosynthesis.
Answer:

In human species, the allele responsible for myopia is dominant over
the allele responsible for normal vision.
A heterozygous myopic man marries a woman with normal vision.
1- Designate, by symbols, the corresponding alleles.
Answer:
'M' for dominant whereas 'm' for recessive allele.
Explanation:
Allele used for myopic man is 'M' whereas the allele used for normal vision is 'm'. The 'M' represents that the allele is dominant and the 'm' refers to the recessive allele. When the dominant allele combine with recessive allele, the organisms have physical features from the dominant organisms while on the other hand, the recessive allele hide and do not appear in the physical appearance of that organisms.
Which subatomic particle is positively charged?
A. Neutron
B. Ion
C. Proton
D. electron
Answer:
Proton
Explanation:
Neutron are neutral, ion I am not sure but are not positive, and electron are -.
Answer: Proton
Explanation:
In an atom there exist three types of sub atomic particles
1) Electrons
2) Neutrons
3) Protons
so we know that electrons are negatively charged particles which stays in a finite orbit as per their energy level
Protons are positively charged particles which remains inside the nucleus and they are tightly bound inside it
Neutrons are neutral sub atomic particles which do not have any charge in it.
So we have correct answer as
D) Proton

2. Blood cells (45%)
Again Blood cells is divided into:
RBC ( Red blood cell)
It transports oxygen for respiration.
WBC ( White blood cell):
They help in the formation of antibodies to fight against germs and bacteria.
Platelets:
It plays major role in healing of the wounds.
What would the control group be?
Answer:
A plant without fertilizers
Explanation:

explain how microbes are (or become) pathogenic
Answer: Microbes that cause disease are called pathogens. It is important to remember that: A pathogen is a micro-organism that has the potential to cause disease. An infection is the invasion and multiplication of pathogenic microbes in an individual or population. Pathogenicity is defined by the capacity of a microbe to cause damage in a (susceptible) host. Virulence is defined as the relative capacity of a microbe to cause damage in a host. brainliest???

What is biomass?Biomass refers to the total mass of living organisms present in a particular ecosystem. Biomass includes the mass of living organisms such as plants, fungi, animals, bacteria, dead organic matter, etc.
Biomass can be used to generate heat or electricity and act as a source of energy by burning of wood or other plant material. It also used to produce biofuels from corn and sugarcane and bioplastics made from plant-based materials.
The biome found in Brazil is savanna. This biome is a tropical grassland ecosystem covering approximately 25 percent of the country's total land area. It involves a mix of grasses, shrubs, and trees, with a distinct dry and wet season, and is a home to a diverse range of species, including jaguars, capybaras, many species of birds, reptiles, and insects.
Therefore, savanna is the biome found in Brazil.

what are the abiotic processes in carbon cycle?
Explanation:
Abiotic processes in the carbon cycles : Management of the carbon cycle is the focus of global warming. Respiration, deforestation, burning of fossil fuels, and forest fires are processes that put CO2 up in the atmosphere. Organisms eat plants, which is comprised of carbohydrates come from CO2 in the atmosphere.
Which of the following is a process used by animals that produces carbon dioxide as a by-product?

Answer:
Factors affects each landforms differently and shapes it depending on the nature of surface.
Explanation:
Water is one of the main erosion agents that help in shaping the lands. The mountains and hilly regions of world are all shaped by the wind and water an important geomorphic agent of change. Water flowing down from mountains has the ability to make various landforms such as V-shaped valleys, steep slopes ridges, and many geographical features. While in deserts water can lead to flash floods. Sheet erosion formation of canyons, gorge, channels, etc.
