Each of two parents has the genotype brown/red​, which consists of the pair of alleles that determine hair color​, and each parent contributes one of those alleles to a child. Assume that if the child has at least one brown ​allele, that color will dominate and the​ child's hair color will be brown. a. List the different possible outcomes. Assume that these outcomes are equally likely. b. What is the probability that a child of these parents will have the red/red ​genotype? c. What is the probability that the child will have brown hair color​? a. List the possible outcomes.

Answer:

There will be 8 adenine bases.

Explanation:

There are total of 4 nitrogenous bases present in a DNA that includes Adenine, Guanine, Thymine, and Cytosine. These nitrogenous bases form complementary base pair in which, adenine form two hydrogen bonds with thymine and cytosine form three hydrogen bond with guanine.

So, if there are 8 thymine bases in a DNA (irrespective of half or full) then there will be 8 adenine bases, forming two hydrogen bond with each other.

Hence, the correct answer is "There will be 8 adenine bases."

Answer:

B. Gene expression is influenced by high lactose levels in the environment.

Explanation:

The lactose operon (lac operon) functions for the metabolism and transport of lactose in several bacteria.

Gene expression is influenced by high lactose levels in the environment as genes are expressed in the presence of high level lactose and absence of glucose. High level lactose carry an activator protein called catabolite activator protein (CAP), which let the RNA polymerase do transcription of the operon.

Hence, the correct option is "B".

Answer:

Hydrophilic portions are outside and hydrophobic regions are inside

Explanation:

A micelle is an assembly of amphiphilic molecules formed in a liquid solution, generally an aqueous solution. Micelles are formed due to the packing (aggregation-like) behavior in which single-tail lipids are organized in a bilayer. A typical micelle in aqueous solution forms a spheric assembly where carboxylate ions are organized in a mode that hydrophilic head regions enter in contact with the surrounding water, while hydrophobic (lipophilic) portions are disposed inside the micelle.

Answer: d. know the father's genotype

Explanation: Butterflies can produce hundreds of offspring per cross. In a certain variety of butterflies, a maternally-imprintable gene is responsible for wing phenotype.

The option that would be helpful in predicting the wing phenotype of a male offspring from such a cross would be to look at the father's phenotype.

Imprinted genes can simply be defined as genes that are expressed in parent-of-origin specific manner and result from a chemical modification of DNAs.  Such genes are differentially expressed depending on which of the two parents they are inherited from. Hence:

Phenotype refers to the physical appearance or expression of a gene. Therefore, if a gene is maternally imprintable, looking at the phenotype of the father would be helpful in predicting the phenotype of the male child in case a cross happens.

Applying the same principle to the butterfly, it will, therefore, be helpful to look at the father's phenotype in order to predict the wing phenotype of a male offspring from a cross.

The correct option is A.

Answer:

The concentration of potassium will decrease

Explanation:

The cochlear ducts are composed of two distict types of fluids: 1-perilymph, rich in sodium (140 mM) and low in potassium (5 mM), and 2- endolymph, rich in potassium (1 mM) and low in sodium (150 mM). The perilymph fluid has a similar composition to the rest of the extracellular fluids, while endolymph present a unique ion composition that is not found in other fluids of the body. It is believed that the cochlea can regulate potassium flow without using energy (i.e.,  without use ATP), since potassium enters into the cells through passive pathways, while this ion ion leaves the cells by an active mechanism.

Answer:

prevents blood from clotting normally due to the body's inability to form fibrin proteins.

Explanation:

Haemophilia is a genetic disorder which could be inherited and it is characterized by constant bleeding and loss of blood when injuries occur. This is as a result of the inability of the body to form fibril proteins. The fibril proteins are responsible for the production of platelets . The platelets are responsible for the clotting of blood.

This validates haemophilia being a disorder which prevent blood from clotting normally due to the body's inability to form fibrin proteins.

Vesicoureteral reflux (VUR)

Explanation:

Answer:

The condition is known as Vesicoureteral reflux (VUR)

Explanation:

Vesicoureteral reflux (VUR) is a pathological condition caused by Urinary Tract Infections (UTIs) where urine flows back from the bladder into one or both ureters, and sometimes back into the kidneys. The condition is commonly seen in young children under 2 years of age, and infants.

Most children with primary VUR were born with an abnormal ureter, which is mainly seen as a defective valve between the kidneys and the ureters that does not close well, hence resulting in refluxes. Secondary VUR develops due to some pathological conditions affecting the urinary tract, like blockage of the urethra, causing reflux of urine. Defective bladder nerves can also lead to VUR.

Catalyze biochemical reactions.

Explanation:

Hello,

In this case, it is widely known that enzymes are able to take substrates or reactants to their active sites, in order to catalyze a raft of biochemical reactions by which products that are not usually formed under typical conditions are formed, and then allow them to dissociate from the surface of the enzyme. Such combination formed by an enzyme and its substrates is called the enzyme–substrate complex which is further taken to the isolated product.

Answer:

Prokaryotic cells' DNA are located in the cytoplasm of the cell rather than in the nucleus, like in eukaryotic cells. DNA aids in protein synthesis and determines functions of the cell in cells, regardless of being within the membrane of a nucleus or not.

I hope this helps a little.

The word prokaryote in Greek means before kernel (nucleus). Unlike the eukaryotic cells, the nuclear material is located in the cytoplasm of the cell in a nucleoid.

The prokaryotic cells are the primitive karyons that are defined by the lack of the true nucleus and organelles. Unlike the eukaryotes, the organelles lack the membrane that covers them but has a tough cell wall.

The prokaryotes include archaea and bacteria which are unicellular and microscopic organisms that are simple and have their genetic material organized into nucleoids in the center of the cell. They have the ability to live in harsh conditions.

Therefore, the eukaryotes and prokaryotes differ in the arrangement of the genetic material.

Answer:

By changing the transition state and pH of the medium

Explanation:

Enzymes are proteins that bind to their corresponding substrates at their active sites in order to form complexes that catalyze specific chemical reactions. A key feature of this process is the fact that both acid and base catalytic activities may be combined in the same reaction. The acceleration in the velocity of the enzymatic reaction due to the addition of acids and bases is known as acid–base catalysis, where the acid or base is not consumed during the reaction. For example, enzymes can partially transfer a proton to the medium, thus changing the transition state of the chemical reaction and also decreasing its pH.
