Explanation:
Let R be the allele for red stripes.
Let r be the allele for yellow stripes.
Parental phenotypes:
Orange stripes * Orange stripes
Parental genotypes:
Rr * Rr
Gametes:
(R)(r) * (R)(r)
Using a Punnett's Square, we get
F1 generation genotypes:
RR : Rr : rr = 1 : 2 : 1
F1 generation phenotypes:
Red : Orange : Yellow = 1 : 2 : 1.
Which recent discovery led to a new understanding of how genetic mutations increase the risk of cancer? double helix structure of DNA BRCA1 and BRCA2 genes nucleic acid monomers formation of tumor suppressor proteins
Answer:
BRCA1 and BRCA2 genes
Explanation:
The BRCA1 and BRCA2 genes are tumor suppressor genes that encode breast cancer susceptibility proteins involved in repairing double-strand DNA breaks (DSBs) by the mechanism of homologous recombination. This mechanism uses the sister chromatid of the homologous chromosome as template for repairing DSBs. It has been shown that mutations in BRCA1 and BRCA2 genes alter the molecular mechanism of homologous recombination DNA repair, thereby mutations are not repaired appropriately and persist in the DNA of tumor cells.
(B.) BRCA1 and BRCA2 genes

Why is it necessarry for DNA to replicate itself?
Answer:
Like Many time's I've looked the answer up ;)
DNA replication needs to occur because existing cells divide to produce new cells. ... So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions!

Explain the difference between AKI and CKD
Answer:
Acute kidney injury (previously called acute kidney failure) is the sudden loss of kidney function, usually as a result of illness, drugs or injury. Acute kidney injury is commonly reversible. Chronic kidney disease (CKD) will progress to chronic kidney failure with time.
Explanation:
Answer:
AKI is reversible (for the most part) where CKD is not
Explanation:
AKI develops very suddenly. It is normally caused by an acute renal insult and encompasses a spectrum of renal impairment from minor changes in markers of renal function. Managing AKI includes; identifying and treating the underlying case and doing your best to minimize as many complications as possible.
CKD develops over time, normally taking a few months to years for it to show itself. It normally comes from having diabetes and hypertension. The disease itself is, more often than not, discovered when going through screening for other, unrelated, diseases. You can slow down the progress of renal failure but you can't treat it. CKD will eventually lead to permanent dialysis or the patient needing a kidney transplant.

While performing strenuous exercise, a person may experience a temporary shortage of
oxygen. As a result, anaerobic respiration supplies the required energy.
What is an end product that will build up in the person's muscles?
A. ethyl alcohol
B. glucose
C. lactic acid
D. pyruvate
Answer:
C. lactic acid
Explanation:
"Lactic acid" build-up in the muscles occur when a person does an "anaerobic exercise," specifically high-intensity ones. Due to lack of oxygen going to the muscles (temporary), "glycolysis" occurs. This means that glucose will be used in order to provide the energy needed. This process produces lactic acid as an end-product. This makes the muscles "sore," thus, it is important to have rests per week in order to eliminate lactic acid.
Compare transport in animals and plants cells
Answer:
Transport in both plants and mammals is by a system of specialised tubes. ... In mammals this forms a circulatory system of arteries, capillaries and veins. In flowering plants, transport is not circulatory and occurs in microscopic xylem and phloem.
Explanation:
Mammals:
ºSpecialised tubes - arteries, capillaries and veins.
ºAll tubes are composed of living cells.
ºThe concentration of substances transported is controlled (see homeostasis). The ºconcentration of the substances being transported is not controlled.
ºThe heart controls the circulatory system. The heart is controlled by the nervous system.
ºThe rate of flow is moderate and is regulated by vasoconstriction and vasodilation.
ºUses water as a medium in which to transport substances (it is a good solvent, it has a high specific heat capacity, has good surface tension but is not viscous, and is unreactive).
º The substances being transported are: respiratory gases, glucose, amino acids, fatty acids, glycerol, vitamins, minerals, hormones.
Plants:
º Specialised tubes - xylem vessels and tracheids and phloem sieve tubes.
º Some tubes are composed of living cells, e.g. phloem. Others are composed of dead cells, e.g. xylem.
º The concentration of the substances being transported is not controlled.
º There is no such control in plants.
º The rate of flow in the xylem and phloem is quite slow. The rate of flow in the xylem is controlled by external factors via the stomata (e.g. temperature, wind, humidity).
º Uses water as a medium in which to transport substances.
ºSubstances being transported are: sucrose, amino acids, fatty acids, glycerol, vitamins, hormones (in the phloem) and minerals and water (in the xylem). Respiratory gases are not transported by this system but move via a series of inter-connecting air spaces.

What is the purpose for mitosis
Answer:
The purpose of mitosis is to make more diploid cells.
Explanation:
Question: How is it that traits can vary so much in the same family?
Answer: One component, called shared environment, includes all environmental influences that make children in a family similar to one another.
Explanation: Environmental variance not due to shared environment is called nonshared environment; this portion of environmental variance makes family members different from one another.
Check all that apply: What are the reasons fungi are NOT plants

All Archaea and bacteria are microscopic, prokaryotic organisms. However, Archaea and bacteria differ in significant ways. Which of the following is the MOST important reason that Archaea and bacteria belong to separate biological domains?
Archaea are often resistant to antibiotics
O Archaea do not have a nucleus
O Archaea are found as single cells or colonies
O Archaea often live in more extreme conditions than bacteria
The most important reason that Archaea and bacteria belong to separate biological domains is Archaea often live in more extreme conditions than bacteria.
What are the examples of biological domains?There are three domains of life, the Archaea, the Bacteria, and the Eucarya. Organisms from Archaea and Bacteria have a prokaryotic cell structure, whereas organisms from the domain Eucary encompass cells with a nucleus.
Examples include memory, mate choice, relationships between kin, friendship and cooperation, parenting, social organization, and status.
This phylogeny overturned the eukaryote-prokaryote dichotomy by showing that the 16S rRNA tree neatly divided into three major branches, which became known as the three domains of (cellular) life: Bacteria, Archaea and Eukarya.
