Are bacteria and viruses bound by a cell membrane or is it exclusive to one of them? Do bacteria and viruses have a nucleus or do only one of them have one?
Answer:
Explanation:Lack membrane-bound organelles - While bacteria have a few organelles involves in metabolism and reproduction, they, like viruses, do not have membrane-bound organelles. In viruses, the nucleic acid is not contained in a nucleus as is the case with eukaryotic cells.

Scientists often use the analogy of a tree to describe the history of life on Earth. All organisms alive today, including archaea, bacteria, and eukaryotes, can trace their development to the same common ancestor or set of ancestors, which forms the base of the tree. Which statement provides the strongest evidence for the conclusion that all living things share common ancestry?
a. All living things perform either cellular respiration or photosynthesis
b. All living things use DNA as a genetic code to transmit information
c. All living things have vestigial structures that are remnants of structures found in ancestral species.
d. All living things are made of cells with approximately the same composition, size, shape, and function
Answer:
B
Explanation:
DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to discover history of a living organism and to produce proteins, which are the complex molecules that do most of the work in our bodies

• sexual reproduction
• diploid
• unique daughter cells
• gametes
• meiosis
• unique
• haploid
• zygote
• identical daughter cells
• mitosis
Answer:
Meiosis is a process in which sex cells, also known as gametes are made. Meiosis is different from mitosis in a lot of ways, one being that mitosis creates identical daughter cells and meiosis creates unique daughter cells. Meiosis is important because it allow for the creation of a meiosis nucleus. Cells produced by meiosis will be used in haploid, where each member of the next generation is genetically unique.
Cells produced in sexual reproduction will have half of the genetic information of body cells and will be genetically unique. This is necessary because when a sperm and an egg fuse together in sexual reproduction. They form a zygote: the first body of a new individual.
The new individual will now have cells that are diploid, meaning they have two sets of chromosomes. They zygote will have to do a lot of mitosis allowing it to grow quickly and ensure that all of its cells are genetically unique.

What are the qualities of greenhouse gas? Select the two correct answers.
A. transparent to infrared radiation
B. three or more atoms in a molecule
C. produced by human activity
D. absorbs and re-emits infrared radiation
E. composed of single atoms, not molecules
I agree with the user's answer above ^. I think both choices suit the qualities of a greenhouse gases. So, yes 'absorbs and re-emits infrared radiation' and 'transparent to infrared radiation' are correct.
Infrared radiation is emitted by greenhouse gases. Therefore, option"A" is correct.
What are greenhouse gases?A gas that can absorb infrared light is referred to as a greenhouse gas. Only molecules with three or more atoms have the capacity to absorb infrared light. Homonuclear diatomic molecules like N2 and O2 don't absorb or emit infrared light because their dipole moments don't alter much.
The quantities of greenhouse gases are influenced by numerous factors. Fossil fuels release CO2 . Since the Industrial Revolution, human activities, particularly the burning of fossil fuels, have led to persistent increases in the atmospheric concentrations of different greenhouse gases, including carbon dioxide, methane, ozone, and chlorofluorocarbons (CFCs).

Why is DNA related to protein
DNA stores the instructions (genetic information) used to build proteins.
In squash plants, yellow fruit (Y) is dominant to white fruit (y). If two plants heterozygous for yellow fruit are crossed, what are the possible genotypes of the offspring?
Answer: YY, Yy, yy
Explanation:
The possible genotypes of the offspring would be YY, Yy, yy.
What do you mean by genotypes?The genotype of an organism is its complete set of genetic material. Genotype can also be used to refer to the alleles or variants an individual carries in a particular gene or genetic location.
Genotype is the genetic make-up of an individual organism. Your genotype functions as a set of instructions for the growth and development of your body. The word 'genotype' is usually used when talking about the genetics of a particular trait (like eye colour).
The different types of genotypes are- homozygous recessive (pp), homozygous dominant (PP), and heterozygous (Pp). The homozygous dominant and the heterozygous genotypes show the same phenotypes.

How have plants adapted to different environmental conditions?
Answer:
Plants adapt to their environment from necessity. Plants may also adapt by growing lower and closer to the ground to shield themselves from wind and cold. Desert environments may have some of the following adaptations, these help the plant to conserve food, energy and water and still be able to reproduce effectively.
Explanation:
Is methemoglobinemia recessive or dominate? Provide examples to back up your answer
Answer:
recessive
Explanation:
The inheritance pattern of the congenital enzyme deficiency form of the disease is autosomal recessive. Hb M is inherited in an autosomal dominant pattern. There is no association between sex and the frequency of congenital methemoglobinemia.
Methemoglobinemia is an autosomal recessive congenital disorder. It means that both copies of the gene are found to be recessive in order to express a phenotype.
What do you mean by the Dominant trait?The Dominant trait may be defined as a form of trait which governs by the presence of at least one dominant copy of that gene.
Methemoglobinemia may be defined as a blood disorder in which very little amount of oxygen is delivered to your cells. Cells may feel the scarcity of oxygen.
If an individual is affected by this disorder, both the copies of its gene are found in a recessive form in order to mask the effect of a dominant copy.
Therefore, it is well described above.
