Two key processes by which organisms produce water are photosynthesis and cellular respiration.
The method that plants employ to produce their own nourishment is called photosynthesis. Plants absorb carbon dioxide from the atmosphere and utilize the sun's energy to transform it into glucose. One kind of sugar that plants need for energy is glucose. Additionally, plants emit water vapor into the atmosphere as part of the photosynthetic process. The method through which organisms get energy from the food they consume is known as respiration. When creatures consume food, the glucose molecules in their cells are broken down, releasing the energy they contain. Water vapor is also produced during this process and is discharged into the atmosphere.
Eventually, the water vapor produced by respiration and photosynthesis condenses and returns to Earth as rain. The cycle is restarted when this rainfall ultimately finds its way back to the oceans.
Therefore, by the process of photosynthesis and cellular respiration, organisms use carbon based molecules to make water.

Although compound microscopes and electron microscopes have some similarities, only _____________ microscopes use light and lenses to magnify objects.
please help me
Answer:
ORDINARY LIGHT
Explanation:
Compound microscopes and electron microscopes have some similarities only light microscopes use light and lenses to magnify objects.
What are light microscopes?A light microscope is an apparatus or tool used in biology labs that employ visible light to find, magnify, and enlarge very minute things. Utilizing lenses, they concentrate light on the specimen, magnifying it to create a picture. In most cases, the specimen is positioned near the tiny lens. The types and quantity of lenses that make up the microscope have a significant impact on the microscopic magnification.
There are two types of microscopes based on the number of lenses used: simple light microscopes, which have low magnification due to the use of a single lens, and compound light microscopes, which have higher magnification than simple light microscopes due to the use of at least two sets of lenses an objective lens and an eyepiece.
The lenses are positioned such that they may bend light for effective picture magnification.
The light microscope's capacity to make a picture by focusing a beam of light through a tiny, transparent object is the foundation for how it works. The picture is then magnified for viewing through one or more lenses. The specimen's transparency makes it simple and quick for light to enter. Bacteria, cells, and other microbial particles can all be included in specimens.
Therefore, although compound microscopes and electron microscopes have some similarities only light microscopes use light and lenses to magnify objects.

A man and a woman marry and have four children with the following blood types: Type A, Type B, Type AB, and Type O. What are the genotypes of the parents? Hint: Work the problem backwards.
Answer:
the man would have type B blood
the women would have type A blood
Explanation:
In the given question, the genotype of the parents are :
- One parent is Heterozygous for A
- Other parent is heterozygous for B
What are the different Blood Groups?Blood is made up of Red Blood Cells, White Blood Cells and Plasma.
There are majorly four type of Blood Groups such as:
- Blood Group A
- Blood Group B
- Blood Group AB
- Blood Group O
Blood group AB doesn't contain any antibodies and thus they lack antigens and couldn't donate it to any other blood group.
Thus AB is a Universal Acceptor.
Blood Group O does not contain any antigen and thus it is the Universal donor.
What is a Genotype?Genotype simply means version of DNA sequence that an individual has. There is a large amount of variation in DNA sequencing among individuals and these sequencing when applied to an individual gene are called as genotype.
Genotype can also be used to refer to the alleles or variants an individual carries in a particular gene or genetic location.
The number of alleles an individual can have in a specific gene depends on the number of copies of each chromosome found in that species, also referred to as ploidy.
What are alleles?Allele is defined as the variant of a given gene.
In genetics it is normal for genes to show deviations or diversity and all alleles together make up the set of genetic information that defines a gene.
In the given question the genotype of the first child would be IAIO and for the second child it is IB IO. For the third child, it is IAIB and the fourth child would be having IO IO.
As children inherit one allele from each parent, these genotypes are possible only when the genotype of parents is IAIO i.e. heterozygous for A and IB IO heterozygous for B.
Thus one parent is Heterozygous for A and other parent is heterozygous for B.
