Answers

Answer 1

Complete question: Sickle-shaped red blood cells result from a mutation in the gene that codes for hemoglobin. This mutation results in sickle-cell anemia. A partial sequence of bases from a normal hemoglobin gene and a sequence that results in sickle-cell anemia are shown below (the diagram is in the attached file)

What type of mutation is depicted in this sequence?

Answer:

The type of mutation is known as SUBSTITUTION.

Explanation:

Sickle cell anaemia is an inherited disease caused by abnormal shape of the red blood cell. This abnormal red blood cell contains less haemoglobin and cannot transport oxygen efficiently round the body. Sickle-shaped (abnormal) red blood cells result from a MUTATION in the gene that codes for hemoglobin.

Mutation is the random changes in DNA that alters genetic information and so introduce new characteristics. The different categories of mutations include:

--> Chromosomal mutation and

--> Point mutation.

SUBSTITUTION is a type of point mutation in which one base is incorrectly added during replication and replaces the pair in the corresponding position on the complementary strand. From the diagram, a partial sequence of bases from a normal hemoglobin gene and a sequence that results in sickle-cell anemia, shows a substitution of an A for the middle T. This leads to GUA in the messenger RNA, which specifies the amino acid valine. The substitution of valine for glutamic acid at this particular position alters the chemistry of the hemoglobin such that it sticks together if it is not binding oxygen, creating sickling of the red blood cells.

What trait would make an individual likely to survive and reproduce in a pest population that feeds on pest-resistant plants?

Answers

Answer:

Upon exposure to insecticides, insects that do not carry the resistance genes die, thus allowing the individuals with the resistance genes to survive and reproduce, creating more resistant insects. With every generation the number of resistant insects increase.

Explanation:

The trait that would make an individual ( pest ) survive in a pest population that feeds on pest-resistant plants is :  Possession of Pesticide resistant genes

In a pest infected population most pests can be eliminated with the use of pesticides. therefore when pesticides are administered in the population, the pests that posses genes resistant to pesticides will survive and continue their reproduction cycle.  while pests without pesticide resistant genes will be eliminated.

Hence the trait that a pest( individual ) should posses to survive in a pest population is; the Possession of Pesticide resistant genes .

how are karyotypes made?

Answers

Answer: A karyotype is simply a picture of a person's chromosomes. In order to get this picture, the chromosomes are isolated, stained, and examined under the microscope. Most often, this is done using the chromosomes in the white blood cells. A picture of the chromosomes is taken through the microscope.

Explanation:

Answer:

Karyotypes are prepared from mitotic cells that have been arrested in the metaphase or prometaphase portion of the cell cycle when chromosomes assume their most condensed conformations. A variety of tissue types can be used as a source of these cells.

Yeast reproduce sexually.

Cattle offspring will have more genetic variation than yeast offspring,

Cattle reproduce sexually.

Yeast inherit genetic material from one parent.

Yeast reproduce asexually

Yeast offspring will be have more genetic variation than cattle offspring.

Answers

Answer:

cattle reproduce sexually

cattle offspring will have more genetic variation than yeast offspring

yeast inherit genetic material from on parent

yeast reproduce sexually

Explanation:

The correct statements are:

Yeast reproduce both sexually and asexually, while cattle reproduce only sexually.

Cattle offspring will have more genetic variation than yeast offspring because cattle undergo meiosis, which shuffles their genetic material, while yeast can reproduce clonally through asexual reproduction or sexually through mating of haploid cells.

Yeast inherit genetic material from both parents during sexual reproduction, while in asexual reproduction they inherit genetic material only from one parent.

Yeast offspring can have more genetic variation than their parents due to recombination during sexual reproduction, while cattle offspring will have a mix of genetic material from their parents due to meiosis.

Describe yeast?

Yeast is a type of single-celled microbe that is a member of the fungi kingdom. Because it is a eukaryotic creature, each of its cells contains a real nucleus as well as other organelles.

Therefore, despite the fact that both yeast and cattle are capable of sexual reproduction, the procedures and results are very different. Cattle can only reproduce sexually, although yeast can also multiply asexually.

Due of the variations in their reproductive systems, the genetic variety in progeny is likewise unique. These characteristics are not important when creating renewable energy sources because they are biological variations between species rather than technological or economical factors.

Which of the following changes takes place during the third trimester of a womans pregnancy

A.) the fetus begins to form teeth
B.) the fetus develops toenails,lips, and eyelashes
C.)The mothers uterine contractions begin
D.) the fetus’s hands and feet appear

Answers

Answer:D

Explanation:

The fetus develops toenails, lips, and eyelashes is the change that takes place during the third trimester of a woman's pregnancy.  Therefore, option (B) is correct.

What happens in third trimester?

By the third trimester, which begins around the 28th week of pregnancy and lasts until birth, the fetus has already formed most of its organs and body parts. During this stage of pregnancy, the fetus undergoes significant growth and development. This includes the development of toenails, lips, and eyelashes. Additionally, the fetus begins to accumulate body fat, and its brain undergoes rapid development.

To answer the other options, the formation of teeth begins during the embryonic stage, which occurs in the first trimester. The mother's uterine contractions typically do not begin until labor, which occurs at the end of the third trimester or later. The fetus's hands and feet appear during the embryonic stage, specifically around the 6th week of pregnancy.

Your first big biology exam is coming up in a few days, and in order to prepare for late-night study sessions, you buy a box of Yummies, a delicious type of snack cake. After checking out the nutrition facts label on the side of the box, you discover that a single Yummie cake contains 4.5 grams of total fat, 27 grams of carbohydrate, 0 grams of fiber, and 1 gram of protein. After eating a Yummie cake, what molecule do you expect to be most abundant in your digestive system

Answers

Answer:

Carbohydrate.

Explanation:

The most abundant molecule that is present in the digestive system is the carbohydrates because the food contains higher amount of carbohydrates. The breakdown of carbohydrates leads to the presence of more glucose concentration in the stomach. The concentration of fats and proteins are low due to the presence of low amount in the food that the person can eats. Fats are converted into fatty acids while on the other hand, proteins are converted into amino acids.

Answer:

True.

Explanation:

Forestry can be defined as the art and science of creating, development, management, conservation and analysis of the living organisms such as plants, trees and woodlands existing in the forest. This is usually done so as to tap into the environmental benefits associated with the forests and to ensure the continuous existence of wildlife, plant growth and development.

Forest Management is a branch of forestry. The field of forest management typically deals with legal, administrative, financial, economical, technical and social aspects of a forest so as to facilitate the smooth running and operation of the forest reserve.

A sustainable forest can be defined as a forest management process which typically involves the plantation of seedlings to replace trees that are being cut down. Thus, sustainable forestry is mainly focused on keeping the natural forest alive.

Generally, certified wood comes from trees grown in sustainable forests i.e responsibly managed forests.

Hence, certified woods are gotten from trees that were harvested in accordance with sustainable forestry.

Answer:

Kingdom Protista was first described by Antony van Leeuwenhoek in 1675. The kingdom includes the majority of unicellular and eukaryotic organisms.

Explanation:

Protists are eukaryotic organisms such that they consist of a well-defined nucleus, membrane-bound cell organelles, and are mostly unicellular. However, some of the protists such as algae perform photosynthesis, some protists exhibit mutualism, and some are parasitic.  

Most of the protists are single cells, but they can exist in multicellular forms, in colonies, and can live as single-cell. Some of the examples include giant kelps, euglena, and diatoms.  

Protists such as alga are capable of performing photosynthesis. Photosynthesis is the process of preparing food in the presence of sunlight, water, and carbon dioxide to yield oxygen and provide energy.  

Protists are one of the diverse kingdoms in the classification of organisms as it comprises moulds, algae, and protozoa. Protists are not classified as plants, fungi, or animals. For example, the division Bryophyte is considered as a primitive division to plants, whereas kingdom Moneran is considered as most primitive.

When eggs and sperm are made, the two alleles for each gene separate when the homologous chromosomes separate during meiosis. Each egg/sperm cell only gets one allele for each gene. Which of Gregor Mendel’s principles is this?

Answers

Answer:

1st law: Law of segregation

Explanation:

Mendel’s First Law: Law of Segregation During each round of meiosis, chromosomes are separated into daughter cells. This means that one half of the genetic material goes to one gamete and the other half goes to the other. Mendel’s first law essentially states that the alleles in one locus segregate into separate gametes.
