Answer:
a mutation that causes female pigs to have less offspring
Explanation:
Answer:
A mutation that causes female pigs to have fewer offspring
Explanation:
In the farming industry, more product is better. If cows produced more milk, farmers would make more money.
If sheep produced more wool, the farmers would profit.
If there was an increased crop yield, the farmers would benefit.
However, fewer pigs means less money, so that is the only possible answer.

Which of the following explains the role of plants in the carbon cycle?*
(1 Point)
Plants transfer oxygen and carbohydrates in the biosphere to carbon dioxide in the atmosphere.
Plants transport carbon dioxide in the atmosphere to groundwater.
Plants transfer carbon dioxide in the atmosphere to carbohydrates in the biosphere.
Plants transfer oxygen in the atmosphere to fossil fuels.
Answer:
Plants transfer carbon dioxide in the atmosphere to carbohydrates in the biosphere.
Explanation:
Plants are unique organisms being that they have the unique ability to manufacture their own food via the process of PHOTOSYNTHESIS. Hence, they are called AUTOTROPHIC. Photosynthesis is the metabolic process by which plant cells make sugar (glucose) in the presence of sunlight.
However, in the photosynthetic process, plants require inorganic source of carbon called CARBON DIOXIDE (CO2) and water to perform the process. The chemical overall reaction of photosynthesis is as follows:
6CO2 + 6H2O → C6H12O6 + 6O2
This explains the role of plants in the carbon cycle as they help transfer carbon dioxide (CO2) in the atmosphere to carbohydrates in the biosphere (living organisms).
Water, carbon dioxide, oxygen, and some other substances can pass through the cell membrane because...

Which of the following best describes the principle of independent
assortment?
Answer:
Law that states that the segregation of any pair of alleles is independent of any other pair of alleles . As a result each pair of gametes receives one member of every pair of alleles.no influences from other alleles is necessary.
Explanation:
Okazaki fragments are formed on which strand?
Answer:
The leading strand is continuously synthesized and is elongated during this process to expose the template that is used for the lagging strand (Okazaki fragments). During the process of DNA replication, DNA and RNA primers are removed from the lagging strand of DNA to allow Okazaki fragments to bind to.
Explanation:

Parent strand of DNA is CCTAGCT. What is the complementary strand?
Answer:
GGATCGA
Explanation:
Adenine goes with thymine and Cytosine e goes with guanine.
Basically A is with T; C is with G
Note that:
C matches with G
T matches with A
In this case, the strand of DNA given is CCTAGCT. The complementary strand would therefore be GGATCGA.

Does your conclusion support or reject your hypothesis?
Your conclusion should only support your hypothesis if your hypothesis is correct if not in the conclusion put what was actually the awnser and how it compared to your hypothesis
how much of dna is being copied during replication
In which place would people most likely use solar energy?
Answer:
where they got a lot of sun exposure during the day
Explanation:
because the solar energy uses sun rays to get the energies supplied and needs longer sun exposure
RNA differs from DNA in that RNA has?
A. a double strand and contains uracil.
B. a single strand and contains adenine.
C. a single strand and contains uracil.
Answer:
C. a single strand and contains uracil.
Explanation:
DNA has 4 bases: adenine, cytosine, guanine, and thymine and is double stranded while RNA is one stranded and instead of thymine, it uses uracil.
Hope this helps :)
What are the 2 laws Mendel came up with?
Mendel's Laws of Heredity are usually stated as: 1) The Law of Segregation: Each inherited trait is defined by a gene pair. ... 2) The Law of Independent Assortment: Genes for different traits are sorted separately from one another so that the inheritance of one trait is not dependent on the inheritance of another.

The graphic shows the island of Krakatoa, which disintegrated in 1889, due to the largest volcanic eruption in recorded history. In
the century since the eruption, the island has re-formed from lava flows. The table above shows the number of species of various
plant types that were found on the island over a 30 year period, since the island re-surfaced above the ocean in the 1950's.
Which groups of plants were probably most active in secondary succession and re-establishing the native habitat?
A)
moss
B)
grasses
small trees

B.
Acquired variation
C.
Increase of genetic diversity
D.

Describe a situation in which a bacteria-free environment would be desirable: not desirable:
desirable: When observing bacteria
not desirable: When eating food.
The mitochondria of eukaryotic cells contain two forms of the EF G protein. EF G1mt acts an elongation factor as expected, but EF G2mt acts as a ribosome recycling factor. Individuals with certain single nucleotide polymorphisms (SNPs) in the EF G2mt gene are known to have an increased number of side effects associated with taking statin drugs that treat high cholesterol. The most common side effect is muscle weakness, but they can be as severe as muscle breakdown and liver failure. Propose a mechanism by which SNPs in the EF G2mt gene may lead to these side effects.
Answer:
The correct answer is - polymorphism mechanism.
Explanation:
Polymorphism mechanism in mitochondrial elongation factor gene EFG2: It involves escalates the atorvastatin toxicity and affects the cell respiratory function. Polymorphisms within the EFG2 factor gene lead to the implication in disease. This gene factor may result in adverse drug reactions such as STATIN, that can leads to side effect to the condition that can affect skeletal muscle severely.
EFG2 plays an essential role which is specific in mitochondrial ribosome recycling. EFG2mt gene is required for cell growth on galactose medium using small interfering RNA splicing of expression in human cell lines.
Such mutation exhibits an atorvastatin-sensitive phenotype and shows less respiratory capacity. this concludes that the first phenotype associated with SNPs in the EFG2mt gene and implicates the human EFG2mt gene as a pharmacogenetic gene for stain toxicity in humans.
Hummingbirds share a mutualistic relationship with the flowers they feed on. Which of
these statements about the relationship between the flower and the hummingbird is true?
Answer:
yes
Explanation:
The honeybee has 32 chromosomes in their somatic cells. They undergo meiosis but can
produce offspring drones without fertilization. How many chromosomes does the drone have?
What does this mean for the drone?
Answer: 32 chromosomes, they are clones of the parent drone
Explanation:
The production of offspring drones without fertilization means that offspring that are produced are produced by mitosis, which results in daughter cells that are clones of the parent. They have the same amount of chromsomes as the parent drone, which is 32.
3. Suppose two animals live in the same loca-
tion and eat the same kind of food. What
adaptation would decrease the competition
between them?
Answer:
One eats during the day and the other eats at night.
Explanation:
Answer:
Well, it really depends on the type of animal (for example water, land). However an adaptation like being able to eat different foods would decrease competition between them as they don't have to hunt the same prey.
Explanation:
I don't really know how to explain this. Sorry if my answer is bad.
b) The frequency of allele A, is 0.3 or 30%. Does this mean that 30% of the individuals in the
population will have an A, phenotype? (1 point)

FOR 100 POINTS! MY LAST QUESTION!!! You have to figure out what sheep in the cloning experiment that produced Dolly had the same DNA and which do not.
Answer:
sheep A had the same DNA and sheep B and C did not provid any of the DNA
Answer:
Sheep A is the only sheep that provided DNA.
Explanation:
DNA is located in the nucleus of a cell. Sheep B did not donate any DNA as the nucleus from its cell was removed. Sheep A's DNA was placed into Sheep B's empty egg cell, and Sheep C served as the foster mother and gave birth to Dolly.
