In cats, coat color is an X-linked trait with incomplete dominance. Yellow coat is caused by the allele XT and black coat by the allele Xt. A tortoise coat is caused by the heterozygous condition. What is the correct way to represent the genotype of a cat with a tortoise coat
Answer:
The correct answer is - XTXt
Explanation:
In the question, it is given that in cats the coat color is an X-linked trait that shows incomplete dominance if present in heterozygous condition.
The allele for yellow allele = XT (it is dominant allele)
The allele for black coat = Xt (it is recessive allele)
The amle cat can not show the heterozygous condition or tortoise coat as they have only one X chromosome so they will be either yellow coat cats or black coat cats.
In female cats the tortoise coat will show when the both allele present together: XTXt due to their incomplete dominance.
How do seed plants loose water, and how do they prevent too much water from being lost.
Answer:
Plants reduce water loss by closing their stomata, developing thick cuticles, or by possessing leaf hairs to increase the boundary layer. Stomata are quick to respond to environmental cues to protect the plant from losing too much water, but still allowing in enough carbon dioxide to drive photosynthesis.Explanation:

Which of the following is another example of an autotroph? a) mushroom b) grasshopper) cactus
Answer:
Cactus
Explanation:
An autotroph is something that produces food from inorganic substances like carbon dioxide. So, most plants are autotrophs due to their photosynthesis. Cactuses use photosynthesis, so therefore, they’re autotrophs.
The other answers are wrong as one, mushroom is a fungi that relays on decomposed organic materials for food, and grasshoppers need grass.
An example of an autotroph among the options is the organism called cactus.
What is an autotroph?An autotroph is any specie that is able to produce its own food. In the ecosystem, the autotrophs serve as producers in the system.
Hence, given the options we have, an autotroph among them is the organism called cactus.

In a one-group pretest-posttest design affected by the problem of testing effects, the reduction found on the posttest is likely to be the result of _____
Answer:
taking the pretest
Explanation:
A one-group pretest–posttest design is a type of research design generally used in behavioral research aimed at estimating the treatment effects on the sample. In this experimental design, the target group of participants is first pre-tested on the dependent variable and, subsequently, post-tested after the administration of a treatment. In consequence, the participants of the target group receive the same treatment and assessment. The problem of testing effects indicates that testing may become a problem when the pretest may change participant's behavior. When there are statistically significant differences between the pretest and posttest data, it is possible to support the working hypothesis.

Which of the following best predicts a long term effect of the differences between the E and Z strains
Answer:The difference between the forms of the sex pheromone 11−TDA produced by E and Z strains will act as a prezygotic reproductive barrier leading to sympatric speciation.
Explanation:The difference between the forms of the sex pheromone 11−TDA produced by E and Z strains will act as a prezygotic reproductive barrier leading to sympatric speciation.
Conducting long-term studies to observe the effects of E and Z strains would best predict the long-term effects of their differences.
What are E and Z strains?In biology, E and Z strains are used to describe different genetic variants or subpopulations of a species. These designations are often used in studies of insects, particularly in the context of reproductive isolation and speciation.
For example, in some species of moths, E and Z strains are distinguished based on differences in the production of sex pheromones. Females of each strain produce different forms of the pheromone, which may act as a barrier to mating between individuals of different strains. Over time, this could lead to the development of distinct populations that are reproductively isolated from each other, potentially leading to the formation of new species. Other factors, such as geographic isolation and genetic drift, may also contribute to speciation in these and other organisms.

Answer the lab question, “What is the effect of the inheritance of one trait on the inheritance of a second trait?” with a hypothesis. Remember that you can either assume that the two genes are independent or that they are linked. What results would you expect in either case?
Answer:
please give me branlist and follow
Explanation:
One hypothesis would be "The inheritance of one trait does not affect the inheritance of another trait". It can be explained with the help of law of independent assortment. It states that the genes are randomly distributed in the gametes, that is, independent of each other.

Explain inputs of photosynthesis and how each is used
Answer:
Inputs are in the other answer, and since you asked I'll give the outputs:
glucose (for the plant - created by the Calvin Cycle [through the input of Carbon dioxide]) and oxygen (which the plant does not require, so it exits the plant - created through the water input)
If you want to get really technical, the input light is absorbed and its energy is used to drive electrons from the water. These electrons generate NADPH, which drives protons across the membrane. The protons will then return to make ATP (which is through ATP synthase). (There are some good diagrams of this you could find on the internet for a better visual if needed, but since they aren't mine, I feel I should not post them)

What is the cell membrane made of? Check all that apply.
proteins
cellulose
carbohydrates
lipids
The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.
What are proteins?Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalyzing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific 3D structure that determines its activity.
What are carbohydrates?A carbohydrate is a biomolecule consisting of carbon (C), hydrogen (H), and oxygen (O) atoms, usually with a hydrogen-oxygen atom ratio of 2:1 (as in water) and thus with the empirical formula Cm(H2O)n (where m may or may not be different from n). However, not all carbohydrates conform to this precise stoichiometric definition (e.g., uronic acids, deoxy-sugars such as fucose), nor are all chemicals that do conform to this definition automatically classified as carbohydrates (e.g. formaldehyde and acetic acid).
What are lipids?
In biology and biochemistry, a lipid is a biomolecule that is soluble in nonpolar solvents. Non-polar solvents are typically hydrocarbons used to dissolve other naturally occurring hydrocarbon lipid molecules that do not (or do not easily) dissolve in water, including fatty acids, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E, and K), monoglycerides, diglycerides, triglycerides, and phospholipids.

Identify the true statements about RNA interference. Duplex RNA (dsRNA) can suppress the expression of a gene. miRNAs are short, single strands approximately 21 nucleotides long. miRNAs suppress gene expression by interfering with transcription. miRNA targets the gene from which it was transcribed. RNA interference can temporarily suppress the expression of a target gene.
Answer:
- Duplex RNA (dsRNA) can suppress the expression of a gene.
- miRNAs are short, single strands approximately 21 nucleotides long.
- miRNAs suppress gene expression by interfering with transcription.
- RNA interference can temporarily suppress the expression of a target gene.
Explanation:
The RNA interference (RNAi) mechanism is a naturally occurring biological process by which an organism suppresses gene expression by using sequence-specific small non-coding RNAs that are complementary to RNA (posttranscriptional silencing) or DNA (transcriptional silencing) sequences. Since its discovery, this mechanism has been exploited in molecular biology to control the expression of target genes. There are different classes of non-coding RNAs which are able to trigger RNAi gene silencing: microRNAs (miRNAs), small interfering RNAs (siRNAs), piwi-interacting RNAs (piRNAs, only present in animals), etc. During their functioning, these non-coding RNAs are loaded into the RNA-induced silencing complex (RISC) to direct them to target sequences and trigger RNAi (for example, by cleaving target mRNAs). miRNAs are short, evolutionary conserved RNAs, that associate to the RISC complex in order to trigger both transcriptional and posttranscriptional gene silencing. During their biogenesis, small non-coding RNAs are double-stranded RNA (dsRNA), but they lose a strand (the passenger strand) when associate with the RISC complex, conserving only one strand (the guide strand) that bind by complementary base pairing to target sequences (either DNA in the nucleus or RNA in the cytoplasm).
