Answer:
This question lacks options, the options are;
A. Enlarged molecules
B. Macromolecules
C. Inorganic molecules
The answer is B
Explanation:
As mentioned in this question, carbohydrates, proteins, lipids, and nucleic acids are the basic biomolecules found in nature. They are all polymeric substances, hence, are made up of smaller units called monomers.
Asides from being biomolecules, these four molecules are also referred to as MACROMOLECULES based on their large size and complex nature. Macromolecules are molecules that are relatively large in size composing of an aggregate of monomer. Hence, these biomolecules are macromolecules.

when measuring the blood pressure, the cuff is deflated until two consecutive beats are heard through the stethoscope. This measurement reflects
Answer: Systolic pressure.
Explanation:
Every time the heart beats, it pumps blood into the arteries, which are vessels through which blood circulates from your heart to your tissues with the oxygen and nutrients they need. Blood pressure is the force of the blood pushing against the walls of the arteries, and is highest when the heart beats, pumping blood, which is measured as systolic pressure (i.e., when the heart contracts). On the other hand, diastolic blood pressure refers to the pressure of blood in the artery when the heart relaxes between beats (i.e., when the heart relaxes). Since there are two types of pressures, blood pressure readings are given in two numbers, with the top number being the systolic pressure and the bottom number being the diastolic pressure.
For example, if the systolic pressure measured in a person is 125 millimeters of mercury (mm Hg) and the diastolic pressure is 85 mm Hg, the blood pressure is recorded as 125/85.
So, the systolic blood pressure is registered with the stethoscope when the cuff is deflated. When two heartbeats are heard, the pressure gauge reading is recorded. When the heartbeat ceases, the cuff pressure is released and the diastolic pressure is measured at this time.
The continental crust covers ____ of the earth's surface a. 40% b. 50% C. 60% d. 70%
Answer:
a. 40 percent
Explanation:
Answer:
a. 40%
Explanation:
The continental crust covers 40% of the Earth's surface.
At 25 to 70 km, continental crust is considerably thicker than oceanic crust, which has an average thickness of around 7–10 km. About 40% of Earth's surface area and about 70% of the volume of the Earth's crust is the continental crust. Most continental crust is dry land above sea level.

According to a recent survey, the tiger is the world's favorite animal. Besides their natural beauty, what else about tigers amazes us? Tigers are some of the most powerful hunters in the animal world. They are the largest animal in the cat family. They can weigh more than 600 pounds and measure as long as 11 feet. They are not only strong but also light-footed and agile. They can easily jump long distances when hunting prey. Tigers can even jump as high as 16 feet in the air! They have extremely powerful jaws. A tiger is strong enough to kill a lion, a bear, or even an elephant.

The water vascular system of echinoderms The water vascular system of echinoderms functions in locomotion and feeding. functions as a circulatory system that distributes nutrients to body cells. moves water through the animal's body during filter feeding. is bilateral in organization, even though the adult animal is not bilaterally symmetrical.
Answer:
The water vascular system of echinoderms functions in locomotion and feeding.
Explanation:
The water vascular system of echinoderms is responsible for the functions in locomotion and feeding. The water vascular system is a hydraulic system that is used by echinoderms for example sea stars and sea urchins, for the purpose of locomotion (movement), food and waste transportation, and respiration. This system is composed of canals connecting numerous tube feet.
You may have heard through various media of an animal alleged to be the hybrid of a rabbit and a cat. Given that the cat (Felis domesticus) has a diploid chromosome number of 38 and a rabbit (Oryctolagus cuniculus) has a diploid chromosome number of 44, what would be the expected chromosome number in the somatic tissues of this alleged hybrid
Answer:
The correct answer is - 2n = 41 chromosomes.
Explanation:
It is given that the cat has a diploid chromosome number of 38 while the rabbit has a diploid number of 44 chromosomes and if they form a hybrid then their expected chromosome number in somatic cells would be -
Cat (2n=38) produces haploid gametes with 19 chromosomes (n-19).
Rabbit (2n=44) produces haploid gametes with 22 chromosomes(n=22)
19+22= 41 chromosomes in the particular hybrid as half number of chromosomes come from each parent.
How many chambers are there in human heart
Explanation:
Your heart has 4 chambers. The upper chambers are called the left and right atria, and the lower chambers are called the left and right ventricles. A wall of muscle called the septum separates the left and right atria and the left and right ventricles. The left ventricle is the largest and strongest chamber in your heart.
Answer:
There are 4 chambers in the human heart
Explanation:
The right Atrium, the left Atrium, the right ventricle, and the left ventricle.

During the process of genetic recombination, crossing over occurs between two nonsister chromatids. DNA segments are exchanged between two nonsister chromatids during meiosis I. None of the above. maternal and paternal chromosomes pair and physically exchange DNA segments. All of the above.
Answer:
DNA segments are exchanged between two non-sister chromatids during meiosis I.
Explanation:
An exchange of chromosome segments or parts between non-sister homologous chromatids occurs which is also called crossing over. This crossing over occurs in the meiosis I that is responsible for the variation in the offspring produced. The formation of hybrid species occurs due to this exchanged of DNA segments between two non-sister chromatids.

Mendel used more than 28,000 pea plants in his experiments. Why is it important that he studied such a large sample of pea plants?
A. The pea plants were very inexpensive.
B. Most pea plants die after producing seeds.
C. Having more samples gave him results that were closer to the predicted ratios.
D. Using more plants made the experiments take less time.
Having more samples gave him results that were closer to the predicted ratios.Mendel's experiments involved studying the inheritance of traits in pea plants. By carefully crossing different varieties of pea plants and observing the traits of their offspring, he was able to formulate the laws of inheritance that are still used today.
What does Mendel's experiments involves?Mendel's experiments involved observing the inheritance of traits in pea plants, which were controlled by genes.
By studying a large sample size of 28,000 pea plants, he was able to obtain data that was much more reliable and accurate. This is because the larger the sample size, the closer the results will be to the expected outcomes or predicted ratios, and any anomalies or errors would be minimized.
This is an important principle in statistics and scientific research, and it helps to ensure the validity and generalizability of the findings.
Additionally, by using such a large number of plants, Mendel was able to minimize the impact of any outliers or anomalous results that might have occurred in a smaller sample. This helped to ensure that his results were as accurate and reliable as possible.

What is an Obligate anaerobe? How do obligate anaerobes, like the bacteria C. Botulinum, get energy ?
Answer:
See the answer below
Explanation:
Obligate anaerobes are microbes that can only survive in oxygen-deficient environments. They are killed by the normal atmospheric level of oxygen and will only thrive in environments whose oxygen levels are lower than that of normal atmospheric level.
Obligate bacteria such as Clostridium botulinum obtain their energy through anaerobic respiration processes such as fermentation and anaerobic respiration. During this process of fermentation, the lactic acid pathway is mostly used but other fermentation pathways such as propionic acid, mixed acid, acetogenesis, and methanogenesis pathways can be used.
Neurospora is an ideal organism to study the effects of genetic mutations because of several reasons. What is one of these
Answer:
Due simple growth.
Explanation:
Neurospora is an ideal organism to study the effects of genetic mutations because it is easier to growth and are simple. Neurospora crassa is used as a model organism because it has a haploid life cycle and easier to grow that makes genetic analysis simple. Analysis of genetic recombination is facilitated by the ordered arrangement of the products of meiosis in Neurospora ascospores so due to simple growth and haploid life cycle we can considered Neurospora is an ideal organism.
