Why are people with type o blood considered universal donars?
Answer:
because they can donate blood to anyone
Explanation:
People with type O- blood are called universal donors because their donated red blood cells have no A, B or Rh antigens and can therefore be safely given to people of any blood group. ... Their plasma does not contain A or B antibodies and can be transfused safely to all blood types.

If an organism's body cells have 12 chromosomes, how many chromosomes will sex cells have? Explain.
Answer:
6 chromosomes
Explanation:
Answer:
The gametes or sex cells produced by the organism will have 6 chromosomes if the organism has 12 chromosomes.
Explanation:
The diploid organism has all chromosomes in pairs, one chromosome inherited from male parent & another chromosome in the pair is inherited from the female parent. If an organism has 12 chromosomes, it has 6 different types of chromosomes, differing from one another in length, the position of centromeres and genes present on these. Six different types of chromosomes constitute a haploid set of chromosomes. Two chromosomes of the same type are called homologous chromosomes and these constitute a homologous pair. The cells producing sex cells or gametes undergo meiosis (reduction division) so that each gamete contains only one chromosome of a homologous pair. The gametes are haploid, having half the number of cells as compared to somatic cells.

what is likely to happen to a water molecule entering lamella in the process of photosynthesis
Answer: Explanation: The granum is a part of the chloroplast. The chloroplast contains the chlorophyll pigment and it is necessary for the trapping of the energy present in the sunlight. As a result of this the photolysis of water takes place and hence water is broken down from water molecule to proton and oxygen

Explain how the flow of energy is linked to entropy and how the law of conservation of matter applies to the carbon cycle
The first law of thermodynamics is equivalent to the law of conservation of energy: energy cannot be created or destroyed; the total amount of energy in the Universe is fixed. Energy can be transformed from one form to another or transferred from one place to another but the total energy must remain unchanged.

What are human body tissues?
made of organs and organ systems
created by humans for the support of the most basic needs
made of elements that cannot be broken down by simple means
large groups of the same type of cell, all working together for one purpose
most basic part of the human body
5. Check Two that apply.
00:40:46
Answer:
Large groups of the same type of cell, all working together for one purpose.
Explanation:
Human tissues are the group of cells that work together to perform a specific function. In tissues, similar type of cells combine together for performing similar function. The cells in tissue are same type means same size and structure. When a group of tissue combine together, it forms organ. These tissue can be broken down into simpler substances which are the cells that are considered as the basic unit of life.

Which of the following is not a difference between photosynthesis and cellular respiration?
Answer: D
Explanation: They both play an important role in the carbon cycle. Photosynthesis removed CO2 from the atmosphere while cellular respiration causes the release of CO2 into the atmosphere.
The others are major differences
Photosynthesis has as its products Starch and O2 while those of cellular respiration are water , CO2 and energy.
The materials needed for photosynthesis are water and CO2 while those for cellular respiration are starch and O2
Photosynthesis occurs in chloroplast while respiration takes place in mitochondria .
Thus the only non- difference is D.
Mushrooms are usually considered part of the microbial world because their fungal hyphae are microscopic. Some mushrooms have a fruiting body known as a ___ that is visible to the naked eye above ground.
Answer:
Basidiocarp
Explanation:
This is a multicellular structure found in mushroom that are visible to the naked eye and are spore producing. They are the structures of which spore producing basidia are formed. They called called false ruffles. The basidiocarps serve as the structure on which the hymenium is produced. They are the fruiting bodies of mushroom.

Which of the following is an accurate statement about pathogens? (2 points)
Infection and disease are caused by pathogens living in infectious agents found in the environment.
Pathogens, which cause infection and disease, are the most abundant organisms in the environment.
Most organisms in the environment are harmless, except for pathogens, which can cause disease.
The environment is rich in infectious agents that transmit disease through pathogens.
Answer:
I believe it is d
Explanation:
The answer is Most organisms in the environment are harmless, except for pathogens, which can cause disease.
The oldest and broadest pathogens are any organism or pathogen that can cause disease. Pathogens are sometimes called infectious pathogens or simply bacteria. The term pathogen came into use in the 1880s.
Pathogens are usually defined as microorganisms that cause or can cause disease. Pathogens are defined as microorganisms that can harm the host.
Various microorganisms can cause illness. Pathogenic organisms are of five main types: viruses, bacteria, fungi, protozoa, and worms. Some common pathogens in each group are listed in the column on the right.
