I Think...
Explanation:
Each protein has a particular structure necessary to bind with a high degree of ... Others, like titin (a protein found in muscle), are very large Organization of Protein Structure ... This single hydroxyl orientation difference does not allow galactose to bind to hexokinase and thus hexokinase exhibits specificity of binding.
Liverworts, like the ones shown here, are nonvascular plants. They do not grow tall. Explain how the tissues in liverworts affect their size.
Guys I'm so confused. Please help!
Answer: The tissue structure of the liverworts restricts them to a type of environment that affects their size.
Explanation:
Nonvascular plants, also called the Bryophytes in Kingdom Plantae, are simple plants that grow in damp places on land and as the name implies, are non vascular plants( that is, they lack vascular tissues). There are three types of nonvascular plants which includes:
--> Mosses
--> liverworts and
--> hornworts.
Liverworts are restricted to a particular size through the type of tissue they have ( non vascular) because it predisposes them to lack conducting vessels like the phloem and xylem found in vascular plants which aids in conducting water and food to various parts of the plants. Also they do not grow tall like the vascular plants because they lack the qualities that will enable them do so, such as roots, stems and leaves.
Nonvascular plants are low-growing, reproduce with spores, and need a moist or damp environment.
a______is a substance or a cgemical compound required by the animal for these productive purposes
Answer:
A nutrient is a substance or a chemical compound required by the animal for these productive purposes .
Explanation:
Nutrients are essential compounds and macromolecules needed for a variety of metabolic processes. Animals show heterotrophic nutrition by consuming organic matter like lipids, fats, and proteins.
Food provides essential vitamins, amino acids and minerals that are used as cofactors and coenzymes in chemical reactions.
For example, animals use carbohydrates as fuel for all metabolic processes.
C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
Purple flowers are dominant to white flowers. A heterozygous purple flower is crossed with a white flower. What are the probabilities of the phenotypes and genotypes of their offspring?
Answer:
50% probability of Pp (purple) or pp (white) genotype.
Explanation:
P = purple gene
p = white gene
Punnet squares show the possible genotypes and probabilities of each genotype in the offspring of a cross:
Purple flower genotype (heterozygous) = Pp
White flower genotype = pp
Punnet Square:
[tex]\left[\begin{array}{ccc}&P&p\\p&Pp&pp\\p&Pp&pp\end{array}\right][/tex]
Potential genotypes for offspring are Pp and pp;
According to the Punnett square, 2 of 4 offspring will have the Pp genotype and the other 2 will have pp genotypes;
This means 2 should be purple and 2 white;
Or, there is a 50% chance of having either genotype, of being purple or white.
Let us assume the following:
Flower color is represented by the allele A.Hence, the dominant purple color would be A, while the alternate white color would be represented by a.From the above assumptions, a heterozygous purple flower would have the genotype Aa, while a white flower would have the genotype aa.
Now, crossing the two flowers:
Aa x aa
Aa Aa aa aa
From the results of the cross, the offspring's genotypes, phenotypes, and their respective probabilities would be as follows:
Aa - purple color - 1/2aa - white flower color - 1/2In order words, the cross will yield offspring with purple color flower (genotype, Aa) and white flower color (genotype, aa) each with 1/2 probability.

what is the difference between a heterogeneous mixture and a homogeneous mixture
Answer:
A heterogeneous mixture is a mixture where throughout the solution the composition is not uniform. Through definition, a single-phase consists of a pure substance or a homogeneous mixture. There are two or more phases of a heterogeneous mixture.
Homogeneous mixture is a mixture which has uniform composition throughout its mass.Example:-air,saline solution,most alloys and bitumen.Heterogeneous mixture is simply any mixture that is not uniform in composition.Example:-Sandy water,Orange juice with pull,cereal in milk.

The type of membrane protein that gives cells specific identity are called:
Markers
Channels
Receptors
Pumps
Aquaporins
Answer:
Membrane markers allow cells to recognize one another, which is vital for cellular signaling processes that influence tissue and organ formation during early development. This marking function also plays a later role in the “self”-versus-“non-self” distinction of the immune response.

Explanation:
Which pathway crosses over in the medulla?
a. Lateral spinothalamic pathway
b. Posterior column pathway
c. Anterior spinothalamic pathway
d. Spinocerebellar pathway
Answer:
B - Posterior column pathway
The only spinal column that does not cross over as it enters the spinal cord is the posterior column. Instead, the medulla oblongata is where the posterior column transitions. Therefore, option (B) is correct.
What is Posterior column pathway?The dorsal column–medial lemniscus pathway (DCML) is a sensory pathway of the central nervous system that conveys sensations of fine touch, vibration, two-point discrimination, and proprioception (position) from the skin and joints. It is also known as the posterior column–medial lemniscus pathway, or PCML.
The only column other than the posterior one to enter the spinal cord without making a crossing is the posterior column. In its place, the posterior column makes a U-turn in the medulla oblongata.
Therefore, option (B) is the correct option.

Is sickle cell gene mutation positive, negative, or neutral?
The majority of mutations have neither negative nor positive effects on the organism in which they occur. These mutations are called neutral mutations. Examples include silent point mutations. They are neutral because they do not change the amino acids in the proteins they encode.

Answer/Explanation:
Two unaffected parents can have affected children, that means cystic fibrosis must be a recessive trait.
The two parents must each have one copy of the cystic fibrosis allele, but are themselves unaffected. By chance, the son (shaded) inherited both of these copies and is affected. The daughter either inherited one or zero copies of the cystic fibrosis allele, as she is unaffected.
