What are the genotypes of the parents shown in this pedigree if the disorder is a recessive disorder? What are the genotypes of the parents shown in this pedigree if the disorder is a recessive disorder?
both parents have the disorder
both parents are DD
both parents do not have the disorder
both parents are dd
Answers
Answer:
If the disorder has an autosomal recessive inheritance pattern, according to the family tree both parents do not have the disorder, but are carriers.
Explanation:
When a disorder or disease is recessive it requires two alleles with the disorder to manifest. In this case, according to the pedigree, both parents must be heterozygous carriers and not present the disorder.
Parents
♂ Dd
♀ Dd
Both without disorder but presenting the altered gene, which makes them carriers.
Alleles D d
D DD Dd
d Dd dd
The offspring of these parents have a 50% chance of being carriers without the disorder, 25% non-carriers, and 25% with the disorder.
In the event that either parent was DD, there would be a 50% chance of carriers without the disorder and no chance of offspring with the disorder, which has a recessive inheritance pattern.

Different RNA have different functions such as the mRNA is the linear form that codes for the polypeptide chain, rRNA is the ribosomal RNA and tRNA is the transfer RNA that carries the amino acid.
What are the functions of the different types of RNA?The RNAs, such as mRNA, tRNA, and rRNA, are synthesized in the nucleus and later come into the cytoplasm in the case of the eukaryotic cell, while the prokaryotes perform all the functions in the cytoplasm. The mRNA is formed by the process of transcription from the gene that carries the genetic information for the polypeptide chain synthesis. The tRNA transports the amino acids and reads the mRNA codons, which have a cloverleaf structure. The ribosomal RNA is made up of rRNA and proteins and takes part in translation.
Hence, mRNA is the linear form that codes for the polypeptide chain, rRNA is the ribosomal RNA, and tRNA is the transfer RNA that transports amino acids.

A student was observing (looking at) a section (part) of cells under a microscope. She noticed (saw) they had a box-like shape, bean-shaped organelles and were green. She also noticed (saw) a nucleus that was to the side of the cell. What was she examining? An Animal Cell A virus A bacterium A plant cell
Answers
Answer:
A plant cell.
Explanation:
Plant cells are part of multicellular organisms. They form tissues and are differentiated. If we see a section of plant cells, we can see that they have a box-like shape. This happens because plant cells, besides the membrane, are surrounded by a cell wall, which is rigid and gives the cell this form.
They also do photosynthesis, which is a metabolic process where they obtain energy from the radiation of the sun. To capture the photons they have pigments, especially a green pigment called chlorophyll. The chlorophyll is not free in the cytoplasm, it is contained in a bean-shaped organelle called chloroplast, and therefore they give the chloroplast this distinctive green color.

the genotype of the offspring would be RB, BR, RB, BR (well the genetic pattern of the fish varies for example the fish could have Bg meaning dominant blue and maybe recessive green im making this up and going into detail too much). the phenotype would have to be some sort of mix.
Explanation:
the genotype is the genes on the inside. i just use a table to mix it and assumed both fish were just pure blue/pure red. the phenotype is what's visible. it would be a mix such as maybe purple or red here and blue there. this is since they are both dominant and have to be expressed. same for blood types (AB blood). sorry for late answer.

Runoff that contains fertilizers can cause increased levels of nitrogen in the ocean. What is a possible result of these increased nitrogen levels that may have harmful effects that can disrupt the diversity of ocean ecosystems?
Answers
Answer:
Explanation:
Increased nitrogen level in ocean water can lead to excessive growth of aquatic plants in the ocean which in turn leads to high oxygen (dissolved oxygen) uptake by these plants when they decompose. The overgrowth of these plants also prevent light penetration in the ocean water. All these can affect other aquatic organisms particularly those that depend on these dissolved oxygen and/or light penetration (such as fish and crustaceans).

A caterpillar has an exoskeleton and feeds on many leaves before it makes a cocoon and becomes a butterfly. Which type of organism is a caterpillar? an autotroph and an invertebrate a heterotroph and an invertebrate an autotroph and a vertebrate a heterotroph and a vertebrate
Answers
Answer:
heterotroph and an invertebrate
Explanation:
Animals have been classified into being AUTOTROPHIC OR HETEROTROPHIC based on their nutrition while they are also classified as VERTEBRATE OR INVERTEBRATES based on their skeleton. A heterotrophic animal is one which depends on other organisms to obtain energy or food while an invertebrate is an animal that lacks a vertebrae column or backbone.
In this case, caterpillars are said to feed on many leaves before it makes a cocoon and becomes a butterfly. This means it relies on plants (leaves) for food, hence, it is HETEROTROPHIC. Also, it has an exoskeleton i.e. skeleton present outside the body. This means that it does not possess any bone inside to form the backbone, and hence it is an INVERTEBRATE.

The cell membrane (plasma membrane) is describe as a highly selective barrier composed of a lipid bi-layer. This structure plays an important role in moving molecules across the cell membrane in order for the cell to maintain homeostasis. If the cell is unable to take in the materials it needs or remove what it does not need, the cell may die. This inability of cells to maintain homeostasis may cause sickness or even death of an organism. Why is it important that the cell membrane is highly selective?
Answers
Answer:
Selective permeability is a property of cellular membranes that only allows certain molecules to enter or exit the cell. This is important for the cell to maintain its internal order irrespective of the changes to the environment. ... Movement across a selectively permeable membrane can occur actively or passively
Explanation:
The cell membrane is highly selective in order to prevent certain ions/molecules from entering or exiting the cell. This feature is fundamental for maintaining the homeostasis of the cell.
The homeostasis of the cell refers to the internal balance that cells must have to carry out their metabolic functions (e.g., reproduction, growth, differentiation, etc).The cell membrane is a highly selective lipid bilayer due substances do not cross it indiscriminately but instead it allows the entry/exit of specific particles into the cell.There are some substances that can move across the cell membrane in favor of a concentration gradient (passive transport) and others that move against a concentration gradient (active transport).In conclusion, the cell membrane is highly selective in order to prevent certain ions/molecules from entering or exiting the cell.
