Normal blood cells slide easily through narrow blood vessels. In sickle cell disease many red blood cells change to a crescent s

hape like a slender moon Crescent-shaped blood cells cause blockages in blood vessels These blockages decrease the transport of oxygen People with sickle cell disease often have sharp pains due to the lack of oxygen in parts of the body Some people have one sickle cell gene and one normal gene They have few defective cells and no symptoms because the sickle cell gene is recessive. How does the method of reproduction in humans result in people getting one copy of a sickle cell gene and one copy normal gene? Describe the process

Answer:

Explanation:

The method of reproduction in humans is sexual reproduction: a type of reproduction that occurs when new organisms are produced through the coming together of genetic information from two individuals of different sexes mostly a male and a female (egg cell and the sperm). The genetic information for making the blood cells; the red blood cells genes in particular exists on chromosomes in the nucleus of the sex cells (egg and sperm cell) also called the gametes. Basically, the DNA provides instructions for the production of mostly all of the body's needs.

The genes coding for the sickle cells which is the abnormal red cell is always inherited in the recessive form meaning both parent has to possess one copy each of the defective gene in their DNA. For humans to get one copy of a sickle cell gene and one copy normal gene; it means one of the parents gametes (be it male or female) contributed the defective chromosome and the other normal gene is contributed by the other parent  during copulation giving rise to an individual that is heterozygous for the trait

For example, the sperm cell with the defective gene fertilizes the egg cell that has the normal copy of the gene producing an heterozgous individual.

From the given clauses and phrases, the independent clause can stand alone as a complete sentence while the dependent clause can not.

Clauses can be dependent or independent clauses.

A phrase is a group of words that do not contain a subject but may contain a verb.

Based on the given options:

  • The independent clause is scientists create this plants and animals through genetic engineering.
  • The dependent clause is " so that people can choose whether or not to consume these foods".
  • The infinitive phrase is "to consume these foods "
  • The gerund phrase is "the labelling of these foods".

Therefore, the independent clause can stand alone while the dependent clause can not.

Many athletes and administrators fear the widespread use of gene doping—the use of gene therapy to modify genes that improve ath
lyudmila [28]

YES THAT FIRST SENTENCE IS VERY TRUE.YES, GENE DOPING IS USED BY MANY ATHLETES AROUND THE WORLD.IT CAUSES SEVERAL EFFECTS LIKE:
 a) increased extraordinary hematocrit
 b) increased thrombotic activity
 c) autoimmune anemia,ETC.
 ANY TWO GENETIC MODIFICATIONS THAT WOULD IMPROVE THE PERFORMANCE OF AN ATHLETE ARE:
 a.gene therapy should be given to produce more hormones in the body.
 b. gene therapy is given to athletes because they have been used to study and model cancer (the oncomouse), obesity, heart disease, diabetes, arthritis, substance abuse, anxiety, aging and Parkinson disease to check for the athletes.

identify a probable reason that the dark moths survived while the light moths did not during the industrial revolution
nignag [31]

Answer:

directional selection

Explanation:

The directional selection is a type of Darwinian selection where a particular phenotype is favored in the population, thereby modifying the allelic frequencies to increase the proportion of the favored phenotype. <em>Biston betularia</em>, also known as peppered moth, is a species that was influenced by directional selection in its recent past. Before the industrial revolution, the frequency of light-colored moths was predominant compared to the darker-colored phenotypes, because this color has higher adaptive fitness in a clean, no pollution environment, thereby light-colored moths were able to avoid predatory birds. However, during the industrial revolution, the frequency of dark-colored moths increased in response to pollution (i.e. darker environment), thereby conferring a higher adaptive fitness to darker phenotypes.
