A. a lamp being turned on

B. a toaster being used to toast bread

D. a car horn honking

Explanation:

Energy transformation is the conversion of one form of energy to another form in accordance with the law of conservation of energy. According to this question, Phil is observing a flashlight, which turns chemical energy (batteries) into light energy.

From the examples given in this question, the following are examples of scenarios that involve energy transformation:

- A lamp being turned on: This converts chemical energy to light energy.

- A toaster being used to toast bread: This converts electrical energy to heat energy.

- A car horn honking: This converts electrical energy to sound energy.

Note that, melting of a chocolate does not transform any form of energy.

Answer:

When the sun rays come down into the atmosphere and the plants on the ground use photosynthesis to reproduce and eat. If an animal, for example, a bunny, eats grass the energy will be transferred to the bunny. If a fox eats the bunny, the energy transfers to the fox. the amount of energy will be reduced each time something is eaten because it keeps being consumed over and over.

Answer:

B) 2N

Explanation:

Body cells have 46 chromosomes and are called 2N cell. It's a diploid cell.

2N = 4 chromatids. During meiosis, the 2N cell divides into 4 nonidentical 1N cells.

Answer:

The more an animals color matches their surroundings, the more likely it is for survival. White rabbits fur matches the snow, and brown rabbits fur blend with the dirt

Explanation:

The colors that stand escape the many would be red and blue and the one's camouflage is mostly brown, green, and yellow, swinging on its place and surroundings.

The prey that is more delicate in color lasts extended. As the duration goes on, the white prey lasts extended than the blue colors as they blend into their surroundings sufficiently.

The green, red, and orange varied practically extinct over the 3 generations because they could be stained easier and could not blend into their surroundings.

The colors were very necessary for how it influenced the people because the more brilliant the color the more predators it's going to seduce and the colors such as green and brown are more camouflage.

The more an animal's color approximates its surroundings, the more possible it is to survive. White rabbit's fur approximates the snow and brown rabbits' fur in combination with the dirt.

Answer:

True the bone cells do have different DNA than blood

Explanation:

Answer:

a) 1/4 or 25%

b) 1/4 or 25%

c) 1/4 or 25%

d) 1/4 or 25%

Explanation:

Both cataracts and bone fragility are dominant conditions and are independently inherited. Let cataracts allele be represented by C and fragile bone by B.

A man with cataracts (CC or Cc) and normal bones (bb), whose father had normal eyes would have the genotype Ccbb. The cataract would be heterozygous because he had a normal eyes father. The affected allele must have been inherited from his mother.

A woman free from cataracts (cc) but with fragile bones (BB or Bb) whose father had normal bone would have the genotype ccBb. The fragile bone would be in heterozygous condition because she had a normal bone father. The affected allele must have been from the mother.

    Ccbb    x    ccBb

Offspring

4 CcBb - cataract eyes, fragile bone

4 ccBb - normal eyes, fragile bone

4 Ccbb - cataract eyes, normal bone

4 ccbb - normal eyes, normal bone

a) Probability that their first child would be from both abnormalities = 4/16 or 1/4 or 25%

b) Probability that their first child would have cataracts but no fragile bones = 4/16 or 1/4 or 25%

c) Probability that their first child would have fragile bones but no cataracts = 4/16 or 1/4 or 25%

d) Probability that their first child would have both cataracts and fragile bones = 4/16 or 1/4 or 25%

Answer:

0.8mm.

Explanation:

If the size of an object is about 1/4th the size of the field diameter so the size of an object is 0.8mm because the fourth part of field diameter is equals to 0.8mm. Due to knowing field diameter of microscope we can calculate the real size of objects that is too small which can't be seen with the naked eye. So one fourth part of field diameter is equal to 0.8mm.

Answer:

Parents: Yellow (Aarr) and Grey (AaRr)

Explanation:

Given:

allele A = yellow

allele R = black,

Heteroozygous = gray

Genotypes of the parents:

yellow (Aarr) - female

gray (AaRr) - gray

cross between these

Parents: Yellow (Aarr)  and Grey (AaRr)

Gametes: (Ar, ar) and (AR, Ar, aR, ar)

F1 (Punnet square)

----|----- AR ------|------- Ar ------|------ aR -----|----- ar

Ar | AARr (gray) | AArr (yellow) | AaRr (gray) | Aarr (yellow)

ar | AaRr (gray) | Aarr (yellow) | aaRr (black) | aarr (cream)

Ratio: 3/8 yellow : 3/8 gray : 1/8 cream : 1/8 black

Explanation:

Guanine(G) pairs with Cytosine(C) through a triple hydrogen bond

Adenine(A) pairs with Thymine(T) in DNA, but in this case Uracil(U) because we have a RNA strand therefore:

1.Cytosine

2.Uracil

3.Adenine

4.Guanine

Answer: Earth Overshoot Day is the calculated illustrative calendar date on which humanity's resource consumption for the year exceeds Earth’s capacity to regenerate those resources that year. The term "overshoot" represents the level by which human population overshoots the sustainable amount of resources on Earth.

Answer:

TNF-alpha is expressed as a homotrimer that exerts its activities through binding to two types of receptors: TNFR1 and TNFR2, which are transmembrane glycoproteins characterized by having an extracellular domain with 4 cysteine-rich domains (CRD 1-4) , each with 3 cysteinecysteine disulfide bonds.

Explanation:

TNF-alpha (Tumor Necrosis Factor), which has the characteristic of being a paracrine signaling ligand, is a pleiotropic cytokine that functions as a mediator of immune regulation, the inflammatory response and apoptosis in some cell types. Receptors in this family are involved, with some exceptions, in juxtacrine signaling; that is, both the ligand and the receptor are membrane proteins with extracellular domains through which signaling is established. The cellular responses promoted by TNF are initiated by its interaction with two different types of cell receptors, the type I receptor (55 kDa) and the type II receptor (75 kDa). Both types of receptors are part of the TNF receptor family, members of which include Fas antigen (apoptosis inducer, also called Apo-1 or CD95), CD27 (T-cell activation antigen), CD30 (lymphoma marker Hodgkin) and CD40 (B-cell antigen), which share the characteristic of cysteine-rich sequences in their extracellular domains. This family of cytokines generate cellular responses that include differentiation, proliferation, activation of NFκB and cell death, promoting the aggregation of receptor monomers, that is, they have a transmembrane domain that participates in the solubilization of the receptor and a domain of intracellular death that is involved in signal transduction. The binding of TNF to TNF-R1 induces a signaling cascade through its intracellular death domain, which subsequently leads to the activation of complex I (or inflammatory) of NFkB and proceeds to the transcription of anti-apoptotic genes, pro- inflammatory diseases and apoptosis complex II (caspases).

Answer: The hair is an outgrowth or appendage that grows from a hair follicle.

Explanation:

The three parts of the hair are cuticle, cortex, and medulla. The cuticle is the hard part made up of scales with keratin protein, cortex is the inner pigmented part, and the medulla is the innermost part of the hair.

During hair examination the type of cuticular scales helps in determining the organism to which it belongs, diameter of the medulla also helps in determining the organism, the DNA analysis of the hair can link to its origin, the detection of heavy metal poisoning like lead, arsenic, and others. Drug abuse details can also be determined by the hair analysis.
