10. What are two examples of "typos" that happen when DNA is being copied?
Answer:
DNA “typos” cause variation
Explanation:
Any time DNA is copied, a mistake or change can occur in the letters of the DNA sequence, or gene. These changes result in variations or differences in DNA from person to person.
The "typos" that happen when DNA is being copied is mutations and variations.
What are mutations?A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke.
Moreover, mutations result either from errors in DNA replication or from the damaging effects of mutagens, such as chemicals and radiation, which react with DNA and change the structures of individual nucleotides.
Therefore, mutations within the DNA are a fairly common event. Mutations are random changes that occur within the sequence of bases in DNA. They can be large scale, altering the structure of the chromosomes.

What distinguishes an acute disease from a chronic disease?
What is the difference between them
Answer:
Acute illnesses generally develop suddenly and last a short time, often only a few days or weeks. Chronic conditions develop slowly and may worsen over an extended period of time—months to years.
Acute diseases refer to the medical condition that occurs suddenly and lasts for a shorter period of time. Chronic diseases develop slowly in our body and may last for a lifetime. Chronic diseases are sometimes fatal.

ovulation is induced by a peak in the secretion of
Ovulation starts when the secretion of Luteinizing hormone (LH) peaks in females.
Ovulation is simply the release of eggs from the ovaries of females. It happens as a part of the menstrual cycles of the female gender.
The release of eggs from the ovary is triggered by an acute rise in the level of LH in females. LH in males stimulates the production of testosterone.

What type of energy is used? Photosynthesis transforms ___________ energy into ___________ energy in ___________ molecules.
Answer:
Photosynthesis converts solar energy into chemical energy that plants use to make glucose so they can grow.
Explanation:
During photosynthesis, solar energy is converted into chemical energy in the form of ATP molecules.
----------------------------------------------------------------------------------------------
During photosynthesis solar energy is converted into chemical energy in the form of energy rich bond of ATP molecule.
ATP (Adenosine triphosphate) and ADP (Adenosine diphosphate) molecules are termed currency of energy. ADP molecule is converted into ATP molecules, whenever energy is available in certain exothermic reactions of metabolism.
ATP molecules are store- house of energy. ATP molecule is broken down into ADP molecule in presence of enzyme ATPase, releasing energy whenever energy is required.
The synthesis of ATP molecules, utilizing solar energy during photosynthesis, is termed photo-phosphorylation.
These ATP molecules produced during light reaction of photosynthesis are utilized in dark reaction of photosynthesis (Calvin cycle).
ATP molecules synthesized during photo-phosphorylation may also be used in other metabolic reactions.
Photo-phosphorylation is of 2 types, i.e. Cyclic and Non-cyclic photo-phosphorylation.
Chlorophyll molecules entrap solar energy . There are 2 types of photo systems in chlorophyll. These are photo-system -I and photo-system-II .
The electrons of chlorophyll molecule of photo-system I get excited which pass through series of electron carriers in electron transport system arranged in the order of decreasing energy level.
During the passage of electrons from carriers of higher energy level to the carriers of lower energy level, the energy is lost which is utilized for converting ADP molecule into ATP molecule.
Photo-system I is concerned with light reaction of photosynthesis only, constituting cyclic photo-phosphorylation.
The electron transport during Photo-system II results in the synthesis of NADPH2 in presence of enzyme NADP reductase. NADPH2 is used in reduction reaction of Calvin cycle.
Both Photo-systems participate in non-cyclic photo-phosphorylation that results in the synthesis of NADPH2 in addition to the synthesis of ATP molecules.

what is the purpose of a salt bridge in the voltaic cell?
Answer:
The purpose of the salt bridge is to keep the solutions electrically neutral and allow the free flow of ions from one cell to another. Without the salt bridge, positive and negative charges will build up around the electrodes causing the reaction to stop.
What is a specific example of competitive advantage exhibited by Darwin’s finches?(1 point)
Birds have one of two forms of the HMGA2 gene.
Female finches mated with males that had similar-sized beak
All of the finches evolved from one ancestral species and adapted to their specific niche.
Medium ground finches with small beaks survived multiple droughts.
Answer:
Explanation:
All of the finches evolved from one ancestral species and adapted to their specific niche. of them evolved from one ancestral species, which colonized the islands only a few million years ago.
Darwin's finches, which was residing in the Galapagos archipelago and Cocos island, constitute an iconic model for studies of speciation and adaptive evolution. All of the finches evolved from one ancestral species and adapted to their specific niche.
What are the characteristics of Darwin's finches?The evolutionary history of Darwin's finches is identified by a gene that explains variation in beak shape within and among species.
The major factor influencing the survival of the medium ground finches is weather and the availability of food.
As all of the finches evolved from a single ancestral species and adapted to their specific niche, it is a specific example of competitive advantage exhibited by Darwin’s finches.
Thus, the correct option is C.

how long after conception can you get a positive pregnancy test
Answer: Although many tests indicate you can test as soon as five days before your next period, the most accurate results will be obtained after you have missed your period and the earliest a test can provide an accurate reading is 14 days after conception. Tests differ in sensitivity in detecting HCG in the urine.
Explanation:
Suppose that a patient is diagnosed with a new disease caused by the buildup of waste material in the body's cells. Which organelle is most likely malfunctioning in the patient's cells?
a) Golgi apparatus.
b) lysosome.
c) ribosome.
d) endoplasmic reticulum.
Lysosome organelle is most likely malfunctioning in the patient's cells (option b),.
The organelle most likely malfunctioning in the patient's cells is the lysosome. Lysosomes are membrane-bound organelles that contain enzymes responsible for breaking down waste materials, cellular debris, and foreign substances. They play a vital role in cellular waste disposal and recycling.
In this case, the patient is diagnosed with a disease caused by the buildup of waste material in the body's cells. This suggests that there is a problem with the breakdown and disposal of waste materials within the cells.
The Golgi apparatus is responsible for modifying, sorting, and packaging proteins for transport within or outside the cell. It is not directly involved in waste material breakdown.
Ribosomes are responsible for protein synthesis and are not directly involved in waste material breakdown either.
The endoplasmic reticulum (ER) is involved in protein synthesis, lipid metabolism, and detoxification. However, its dysfunction would not directly result in the buildup of waste material in the cells.
Therefore, considering the role of lysosomes in waste material breakdown, it is most likely that the malfunctioning organelle in the patient's cells is the lysosome. This malfunction would lead to the accumulation of waste material, causing the disease symptoms.

Why is ATP known as the energy currency?
5 line answer plz
Answer:
ATP is commonly referred to as the "energy currency" of the cell, as it provides readily releasable energy in the bond between the second and third phosphate groups. ... As a result, cells within the human body depend upon the hydrolysis of 100 to 150 moles of ATP per day to ensure proper functioning.In addition to providing energy, the breakdown of ATP through hydrolysis serves a broad range of cell functions, including signaling and DNA/RNA synthesis. ATP synthesis utilizes energy obtained from multiple catabolic mechanisms, including cellular respiration, beta-oxidation, and ketosis.
