In what phase is the cell growing and replicating dna before mitosis and meiosis starts?.
Which of these substances are considered hazardous waste? *
A. Corrosive materials
B. Flammable materials
C. Chemically active materials
D. All of the above*
Answer:
D. All of the above
Explanation:
Hazardous waste is defined as waste that comprises organic or inorganic components or compounds that may have a negative influence on human health or the environment due to the waste's intrinsic physical, chemical, or toxicological characteristics.
Correct Option Is D. All of the above.
Liquids, solids, and enclosed gases can all be hazardous waste. Hazardous substances have one or more of the following characteristics: they are combustible, corrosive, lethal, or reactive. They can be waste from manufacturing operations, discarded used materials, or unused commercial products like cleaning fluids (solvents) or insecticides that have been discarded.

HELP ITS TIMED!: Duchenne muscular dystrophy is caused by a recessive allele located on the X-chromosome. Two unaffected people have a child with Duchenne muscular dystrophy.
What is the genotype of the mother?
Question 2 options:
XDXD
XDXd
XdXd
Answer:
XDxd
Explanation:
the recessive allele for the disease is represented by (d).
the dominant allele for not having the disease is represented by (D)
in order to not be affected, we know that the mother must have one uppercase D, so the last option is wrong. And in order to pass it on to her child, she needs one lower case d (to give to the child). So the second answer is correct. good luck :).
What happens during the carbon fixation stage of the calvin cycle.
Answer:
The Calvin cycle, light-independent reactions, bio synthetic phase, dark reactions, or photosynthetic carbon reduction (PCR) cycle of photosynthesis are the chemical reactions that convert carbon dioxide and hydrogen-carrier compounds into glucose. The Calvin cycle is present in all photosynthetic eukaryotes and also many photosynthetic bacteria. In plants, these reactions occur in the stroma, the fluid-filled region of a chloroplast outside the thylakoid membranes. These reactions take the products (ATP and NADPH) of light-dependent reactions and perform further chemical processes on them. The Calvin cycle uses the chemical energy of ATP and reducing power of NADPH from the light dependent reactions to produce sugars for the plant to use. These substrates are used in a series of reduction-oxidation reactions to produce sugars in a stepwise process; there is no direct reaction that converts several molecules of CO₂ to a sugar. There are three phases to the light-independent reactions, collectively called the Calvin cycle: carboxylation, reduction reactions, and ribulose 1,5-bisphosphate (RuBP) regeneration.

BRAINLIEST PLZZZ
Answer:
Store and transmit genetic information: nucleic acid
Are primarily used to store energy: lipids
Help regulate cell processes: proteins
Are used for main source of energy: carbohydrates
Explanation:
Nucleic acid is an important macro molecule that deals with storing and expressing genetic information. The information is encoded by Deoxyribonucleic acid for making essential proteins.
Lipids are structural components of cell membrane which store energy. They are also known as fats.
Proteins is responsible for regulating all cellular process. It is the building block of any organism
Carbohydrates when broken down into glucose release energy and hence they are the major source of energy for our body.
Hence, the correct pair is
Store and transmit genetic information: nucleic acid
Are primarily used to store energy: lipids
Help regulate cell processes: proteins
Are used for main source of energy: carbohydrates
three ways in which an egg cell differs from other cells in the
human body.
Explanation:
1) Egg cells only have half the DNA of the organism
2) in an egg cell the DNA from Mum and the DNA from that is mixed up rather than kept separate
3) egg cells are very large compared to the other cells
Answer:
➢ egg cells only have half the DNA of the organism.
➢ in an egg cell the DNA from mom and the DNA from dad is mixed up rather than kept separate.
➢ egg cells are very large compared to the “other cells.” Although still very small, in humans it's actually the only individual cell you can see without a microscope.

What determines why some traits are "favorable"?
Record your observations of the light in each bin.PLEASE I NEED HELP NOW!!!
Answer:
1. visible light
- the light that humans can see - between 700 nanometers and 400 nanometers
2. ultraviolet waves (UV Rays)
- smaller frequency and higher energy than visible light- between 400 nanometers and 10 nanometers
- the sun emits UV rays - they cause sunburn
3. X-rays
- higher energy and frequency than UV rays
- X-rays can pass through skin and flesh, but not through bone, so they are used to examine bones

Will multiple births, when many egg cells are fertilised outside the body and then implanted, produce identical or similar offspring?
Answer:
The gene that contains the genetic information for brown eyes is said to be dominant. This means that if a person’s body cells contain one gene for brown eyes and one gene for blue eyes, the blue-eyed gene is not allowed to work; it is said to be recessive. The person will have brown eyes. Explain how two parents might have a child with blue eyes even if they both have brown eyes.
Answer:
ill give branliest if you answer
Answer:
brown-eyed parents can pass a recessive blue-eyed gene
Explanation:
the blue eyed gene may be "trapped" for a long time, we also see this outcome in northern africans, they have turkish descent, but still dark skinned (majority), while others have white skin, but both dark/brown parents.
Mangrove forests were traditionally viewed as unhealthy, unproductive environments. Please select the best answer from the choices provided T F.
Mangrove forests or swamps grow in saline and humid region of the tropical and subtropical areas. They were considered unhealthy, unproductive environments.
What are mangroves?Mangroves are special forest trees that are found in regions of high salinity. In earlier times they were considered unhealthy and unproductive for the environment.
They were seen as of no importance and the people wanted them to remove the trees so the environment can become healthy again.
Its ecological value was not known at that time and was considered a waste and mess. But now people have to account for their importance of them as they help to improve the water quality and aid as the breeding place for the fishes.
Therefore, the statement is true.

Explanation:
During which of the following processes would carbon most likely be required? Breaking of rocks Generation of electricity Making of glucose Running of cars.
Carbon is non-metal and is one of the constituents of atmospheric gases and is used for various purposes. It is an element needed in glucose production.
What are the uses of carbon?Carbon is one of the major reactants of the photosynthesis process. Carbon along with the water vapours yields glucose which is a simple sugar. It is used from carbon dioxide in photosynthetic reactions.
Breaking of rocks, running cars and the generation of electricity does not need carbon necessarily. The process of breaking rock and electricity generation uses electrical and chemical forces, while the running of cars can use some carbon in their fuel structures.
Therefore, option C. making of glucose most likely requires carbon.

how does the embryo get nourishment inside the mother 's body
A growing embryo in the uterus derives nourishment through the placenta.
Embryo's nourishmentAn embryo in the uterus gets the necessary nutrient through its connection to the placenta by the umbilical cord.
The necessary nutrients get to the embryo by diffusion from the placenta while waste materials from the embryo diffuse to the opposite side.
A network of blood vessels on the placenta makes the diffusion of nutrient/waste materials possible.
