Answer:
Different genotypes don't always produce different phenotypes because though AA & Aa are different genotypes, they are both dominant, therefore having the same phenotype.
Explanation:
Genotype:
AA Aa aa
↓ ↓ ↓
Phenotype:
dominant dominant recessive
(same phenotype) (different phenotype)

Describe the impact medical and ethical issues pertaining to biotechnology
Answer:
Ethical issues that arise from modern biotechnologies include the availability and use of privileged information, potential for ecological harm, access to new drugs and treatments, and the idea of interfering with nature. Applications include agriculture and health care.
why are manure better than fertilizers
Manure is better than fertiliser. Manure is derived naturally and adds a lot more than just nutrients to the soil. They increase the activity of the microbes in the soil and increase its fertility. On the other hand, fertilisers harm these microbes and cause health issues in the consumers since they are synthesised chemically.

Why are recessive traits shown less than dominant traits?
Answer:
Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive. Recessive traits are found in fewer individuals as it can only be expressed in hom.ozygous condition. In a monohybrid cross between heterozygotes there is only 25% chance of recessive trait being expressed and 75% chance of dominant trait being expressed. Therefore in a population dominant trait is more apparent.

How do mutations occur in the genetic code? This represents crossing over during meiosis.
a) During DNA replication, the original DNA strand GTC ACA GGC ATC is copied into complementary strand CAG CCG TAG. This is an example of deletion.
b)Mutations can only occur when passed on thorough reproduction. The majority of mutations are the result of exposure to mutagens.
c)A woman who has sickle cell anemia passes this disease on to her offspring. This means that the mutation for sickle cell anemia MUST occur in the woman’s gametes.
d)Mutations can be silent and not affect the organism that has them

Explanation:
DNA polymerase only travels in the__________to________direction.
Answer:One Direction
DNA Polymerase Only Moves in One Direction
Explanation:
After a primer is synthesized on a strand of DNA and the DNA strands unwind, synthesis and elongation can proceed in only one direction. As previously mentioned, DNA polymerase can only add to the 3' end, so the 5' end of the primer remains unaltered.
A medicine e.g penicillin which is developed from organism e.g bacteria or fungi and used to fight infections caused by either bacteria or fungi give the correct biological term
Answer:
Penicilium chrysogenum
Explanation:
Answer:
They are generally called antibiotics.
Light travels through the eye by entering through the protective layer called the cornea (17). It then moves through the opening of the pupil which is surrounded by the iris (18), which is a muscle. It will then go through the transparent structure behind the pupil known as the ______________(19) that changes shape to help focus images on the retina in a process known as ________________ (20) The retina contains the photoreceptors known as the _________________(21) and ________________(22). It is there that the actual process of transduction occurs when the photoreceptors excite the ________________(23) cells which in turn send the message on to the _______________(24) cells whose axons make up the optic nerve. The information will then travel to the ____________________(25), which is the sensory switchboard within the brain and end up in the ____________________ (26) lobes where the information is processed specifically within the primary ____________________cortex (27).
Answer:
The correct answer is - 17) Cornea , 18) Iris , 19) Lens, 20) Accommodation , 21) Rods, 22) Cones, 23) Bipolar, 24) Ganglion , 25) Optic Nerve, 26) Occipital, 27) Visual.
Explanation:
The protective layer called the cornea that allows light to enter travel through it to the eyes. Light moves through the pupil surrounded by the muscle called the iris and travels through the lens, a transparent structure that changes its shape on the basis of the intensity of light to help focus images on the retina during the accomadation process. Photoreceptors that are present in the retina are called cones and rods.
The process of transduction takes place when these photoreceptors excite bipolar cells to send signals or messages to the ganglion cells that have axons that make the optic nerves, the sensory switchboard within the brain, and get the messages sent by the photoreceptors. These optic nerves end in occipital lobes where all the signals and messages are processed specifically within the region called the primary visual cortex.
i am ATP producing factory
Answer:
The correct answer is - Mitochondria.
Explanation:
Cellular respiration is the process that produces energy in the form of ATP from converting sugars into carbon dioxide. Cellular respiration is the process that takes place in the mitochondria organelle of the cell.
Mitochondria is known for the production of ATP and therefore called the powerhouse of the cell or ATP producing factory. These ATPs are used as the cellular currency of energy that is used to produce cellular functions.

Answer:
Allele G represents the strong jaw, and allele g represents the weak jaw. This is because as the generations go by, allele G’s population increases, but allele g’s population decreases. If hard shelled animals are the only foods available to them, you would need a strong jaw to eat them. This means that allele g wouldn’t be able to eat these reptiles, so their population would decrease from lack of food.

Is a meander predominantly formed by erosion or deposition?
Answer:
Meanders change position by eroding sideways and slightly downstream. ... Thus by eroding its outer bank and depositing material along its inner bank, a stream moves sideways without changing its channel size. Due to the slope of the channel, erosion is more effective on the downstream side of a meander

1. which model best shows the prediction of growth for a population when taking into account the carrying capacity of its environment?
a. logistics model of growth
b. capacity model of growth
c. mathematical model of growth
d. exponential model of growth
2. which of these contribute to the carrying capacity of a population?
a. environmental conditions
b. density-independent factors
c. weather conditions
d. density-dependent conditions
3. which of these limit population growth?
a. density-dependent factors
b. all limiting factors
c. density-independent factors
d. environmental factors
4. which of the following is a density-dependent factor?
a. hurricane
b. water availability
c. warm weather
d. forest fire
Answer: 1. a. logistics model of growth
2. a. environmental conditions
3. b. all limiting factors
4. b. water availability
Explanation:
1. a. logistic model of growth will show the increase in population of a species in accordance with the carrying capacity exponentially but when the population will experience the scarcity of resources it will decline considerably.
Carrying capacity is the total number of members of the population of a species that an ecosystem can sustain by providing resources.
2. b. All environmental conditions which favor the survival of the living beings will contribute to the carrying capacity for example food, water, shelter, and other resources.
3. b. Limiting factor is the one which limit the chances of survival and growth of a particular species in an ecosystem. For example, scarcity of food, here food is the limiting factor.
4. d. A density dependent limiting factor is the one which affects the population of the species based upon the density. The water availability is a density dependent limiting factor because the more the density or abundance of a population more will be the scarcity of water as it will be required by all organisms. So, the species population may experience decline due scarcity of water.
A genome-wide association study involves searching the genomes of many people in order to find genetic variations associated with common diseases such as cancer, asthma, and diabetes. These studies are possible because of computer databases that allow researchers to compare the genomes of people who do not have a particular condition with the genomes of people who have the condition. In order to do this type of testing, researchers need blood samples or cheek swabs from people. Obtaining these samples is necessary because blood and cheek cells contain___________
A. plasma and platelets
B. a complete set of DNA
C. essential proteins and amino acids
D. a large number of neutrophils
Answer: B. a complete set of DNA
