Answer:
Chemical change is a change in which there is rearrangement of atoms and thus new substance is formed. There may or may not be a change in physical state.
Photosynthesis is a phenomenon in which green plants containing chlorophyll use sunlight as a source of energy to convert carbon dioxide and water to form glucose and oxygen. The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar and oxygen gas.

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.

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.

Answer:
Explanation:
Less broadly, atheism is a rejection of the belief that any deities exist. In an even narrower sense, atheism is specifically the position that there are no deities. Atheism is contrasted with theism, which in its most general form is the belief that at least one deity exists.

What was the laws of heredity
Answer:
Mendel's Laws of Heredity are usually stated as:
1) The Law of Segregation: Each inherited trait is defined by a gene pair. Parental genes are randomly separated to the sex cells so that sex cells contain only one gene of the pair. Offspring therefore inherit one genetic allele from each parent when sex cells unite in fertilization.
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.
3) The Law of Dominance: An organism with alternate forms of a gene will express the form that is dominant.
Explanation:The genetic experiments Mendel did with pea plants took him eight years (1856-1863) and he published his results in 1865. During this time, Mendel grew over 10,000 pea plants, keeping track of progeny number and type. Mendel's work and his Laws of Inheritance were not appreciated in his time. It wasn't until 1900, after the rediscovery of his Laws, that his experimental results were understood.

A dog breeder is looking into purchasing a 3 year old male dog for her business. A breeder online is advertising purebred males for $700. What would you suggest the breeder do before she purchases this dog?
Answer:
The dog breeder to check for all the details that meets her requirement of dogs.
Explanation:
A dog breeding is the practice of mating dogs. In the context, it is given that a dog breeder wants to purchase a male dog of three year old for her business and she founds an advertisement on the net about a purebred males that costs $700. Now before buying this purebred male dog, the dog breeder should first of all check whether the seller who is selling online is a licence breeder or not.
The dog breeder should also check whether the dog is a purebred or not and should also find out the actual age of the dog. The health of the dog should be checked by an professional vet before buying the dog.
The selling of dogs, either a hybrid or a purebred costs differently. An individual should check the license and health of the dogs before purchasing.
In the given example, the dog breeder is trying to purchase a three-year male dog. She saw an advertisement that the male dog is available at the rate of dollars 700.
Before purchasing the dog, the breeder should check:
the authenticity of the advertisementrespective seller details and valid contact information the genotype of the dog as claimed purebred, and the health of the dog from a professional veterinarian.

Explanation:
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

What is the longest phase of the cell cycle and why?
Answer:
Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells. The prefix inter- means between, so interphase takes place between one mitotic (M) phase and the next.
