The given blank can be filled with the sewers cannot handle the volume of waste from street runoff and sewage.

The combined sewage system is very popular in many big cities. The sewage system handles all the sewage combining from the houses. During the rainy season, the water flows in the sewer, causing the overflow of the sewers and spread of water in the nearby regions.

Answer:

Broca’s area is the area of the brain that controls speech production. It was discovered by Paul Broca after he discovered a lesion in the left frontal lobe of a patient who could not speak. Wernicke’s area is the area of the brain that controls speech comprehension. Like Broca’s area, it also plays a role in speech production. Wernicke’s area was discovered by Carl Wernicke, who found that damage to the left temporal lobe resulted in speech deficits.

Borderline personality disorder refers to a kind of mental illness, which is signified by an ongoing pattern of differing moods, behavior, and self-image. In the second stage of borderline personality disorder, the patients are been permitted to demonstrate their physical emotions that the patient is avoiding for some time.

The objective of this stage is that the patient fully expresses his or her emotions. The correct answer is option C that is, discussing the loss of her parents at the age of five and how this is associated with Alvira's current emotional issues.

Answer:

Atomic number, mass number.

Explanation:

The three sub atomic particles of the atoms are electron, proton and neutron. The atomic number of the element is equal to the number of protons of the element.

Isotopes may be defined as the elements that have the same atomic but different mass number. The simplest example of isotopes are protium, deuterium and tritium. They have the same atomic number 1. These are the isotopes of hydrogen.

Thus, the correct answer is option (A).

Altering the environmental conditions will affect the growth of radish seedlings. When radish seeds are developed in environments with different light obtainability, seeds that have less light available will exhibit etiolation. Etiolation is regarded as having long pale yellow color stems and small leaves. On the other hand, seeds that have sufficient light available will be sturdier, green and tinier. 

Answer & explanation:

When we refer to macronutrients, we talk about proteins, carbohydrates and lipids.

In a meal, carbohydrates are usually in greater quantity than proteins and fats, and are primarily used as fuel for metabolic processes.

Carbohydrates have on average 4 kcal per gram (or 17 kJ/g), proteins also have 4 kcal/g, but fats are approximately 9 kcal per gram (or 37 kJ/g).

Thus, fats have a higher energy charge compared to proteins and carbohydrates, although they are not primarily used as cellular fuel.

Final answer:

The diversity among DNA molecules comes from the sequence of nucleotides, which can create a vast number of combinations despite having only four types. Mutations contribute to this diversity by altering DNA sequences, leading to variations among individuals.

Explanation:

The diversity found among DNA molecules is due to the sequence of nucleotides. Even though DNA consists of only four different bases — adenine (A), cytosine (C), guanine (G), and thymine (T) — the arrangement of these nucleotides can vary infinitely. Each organism has a unique DNA sequence, which serves as a genetic blueprint vital for its development, functioning, and reproduction. This genetic diversity is the foundation of the wide variety of life on Earth.

Mutations are changes in the nucleotide sequence that can occur spontaneously or due to external factors like radiation or chemicals. These mutations can lead to variations among individuals within the same species, contributing to the biological diversity we observe. Such variations include single nucleotide polymorphisms (SNPs), which are differences in single nucleotides between individuals, further highlighting the role of nucleotide sequences in genetic diversity.

Answer:

The bases found in a DNA strand are adenine (A), thymine (T), guanine (G) and cytosine (C).

Explanation:

Nitrogen bases are compounds that are part of the composition of DNA and RNA, which are the nucleic acids found in living organ cells.

They are five and can be classified into two types:

DNA is composed of the following bases:

Diffusion is best described as the process where molecules move from an area of higher concentration to one of lower concentration by random molecular motion, until there's uniform distribution. It does not need an energy input.

The best choice that describes the process of diffusion is option A. Diffusion is the movement of molecules from an area of higher concentration to one of lower concentration, driven by random molecular motion. This tends to happen until the concentration of molecules is uniform throughout. It is a naturally occurring process and does not need an input of energy from the system. For example, if you were to open a bottle of perfume in a room, it would eventually spread out, or diffuse, until the smell is evenly distributed in the room.

High blood pressure

The right option is b.Gestational hypertension

Gestational hypertension is a common condition that occurs in healthy pregnant women. Gestational hypertension is characterized by high blood pressure during pregnancy. This form of hypertension develops after 20 weeks of gestation. Symptoms of gestational hypertension include increased blood pressure, sudden weight gain, headaches, nausea and vomiting.

During superposition of a wave such as that of the oceans, when the crest and the trough meet, then they cancel out into the period. If two crests meet up, they add up to a crest that’s equivalent to the summation of their amplitudes. This is also true when two troughs meet up.

This is because, people, generally, have two kidneys and are also able to function properly with one functional kidney. Therefore it is easier to perform kidney surgery without putting the patient’s life at risk as compared to heart surgery. Everyone has one heart, a critical organ whose surgery has to be well planned and done only if the risk of not doing the surgery outweighs that of doing the surgery.

Amyloid precursor protein (APP) is an integral membrane protein expressed in many tissues and concentrated in the synapses of neurons with unknown function. APP is the precursor molecule whose proteolysis generates beta-amyloid (Aβ), a whose amyloid fibrillar form is the primary component of amyloid plaques. Amyloid plaques are found in the brains of Alzheimer's disease patients. APP gene is triplicated in patients with Down’s syndrome. As a result, an amyloid deposition which is associated with Alzheimer's disease is present in all Down syndrome patients older than 30.

Out of the following given choices;

A)the offspring will have traits of both parents.

B)there is genetic variation among the offspring.

C)all the offspring will be genetically identical.

D)none of the offspring will be genetically like the parents.

The answer is C. This is because, in binary fusion, they are no formation of gametes. Therefore genetic variability that comes with sexual reproduction not found in asexual reproduction. Mostly, the offspring buds off from the parent or grows from a split part of the parent. Therefore the offspring is genetically identical to the parent

Without the specific offspring genotypes, the most likely genotypes of the parents are inferred to be heterozygous (Bb) based on Mendelian inheritance patterns.

The question given pertains to the inheritance patterns and predicting offspring genotypes using Mendelian genetics principles. The scenario hints that the parental generation is likely composed of heterozygous individuals because the offspring exhibit a variety of genotypes typically resulting from a heterozygous cross. To answer this with high accuracy, one would need the precise phenotypes or genotypes of the offspring. Assuming a Mendelian trait with simple dominance and using the provided information, if offspring show a typical 3:1 phenotypic ratio, or a 1:2:1 genotypic ratio with the presence of dominant and recessive traits, we can infer the most likely genotypes of the parents to be heterozygous (Bb).

  The most likely genotypes of the parents are Bb and bb.

  In Mendelian genetics, feather color in chickens is determined by a single gene with two alleles: B (black feathers) and b (white feathers). The capital letter represents the dominant allele, and the lowercase letter represents the recessive allele. Black feathers (B) are dominant over white feathers (b). Looking at the offspring, we can deduce the genotypes of the parents.

  Since the first, third, and fifth offspring have black feathers, the only way that can happen is if the parent contributing those alleles has at least one dominant B allele. The second and fourth offspring have white feathers, which means they inherited a recessive b allele from both parents. Therefore, the genotype of the first parent is likely Bb, and the second parent is bb.

  This conclusion is supported by the fact that the black-feathered offspring can inherit either a B allele or a b allele from the Bb parent, resulting in black feathers. Meanwhile, the white-feathered offspring must inherit a b allele from each parent (bb) to express the recessive trait. Thus, the most likely genotypes of the parents are Bb and bb, which is consistent with the observed phenotypes of the offspring.

Complete question: Two chickens are bred and have five offspring, shown below. What are the most likely genotypes of the parents?

Offspring:  

1. Black Feathers (B_)  

2. White Feathers(bb)
