Explain How does DNA direct the cell's activities, such as making proteins DNA stays inside the nucleus?​

Answers

Answer:

Explanation: The nucleotide sequences that make up DNA are a “code” for the cell to make hundreds of different types of proteins; it is these proteins that function to control and regulate cell growth, division, communication with other cells and most other cellular functions. ... This process is called protein synthesis.

Identify the organelles in the cell. Label A Label B Label C Label D

Answers

Answer:

This question is incomplete

Explanation:

This question is incomplete but the completed/similar question with the diagram is in the attachment below.

First of all, the cell is a plant cell because of the presence of the large central vacuole present and also the green colour of the outer part of the cell (which is not a coincidence). Let's proceed to identifying the organelles.

Label A is the large central vacuole. This is not the nucleus as might be confused with because the nucleus is the next big reddish organelle to the right of the vacuole.

Label B is the cell wall. Because this is a plant cell, it has a cell wall which can be clearly seen to be the most outermost layer. While the next yellow boundary line is the plasma membrane.

Label C is the chloroplast. Recall from elementary biology that the chloroplast stores the green pigment chlorophyll. The green colour of this internal organelle makes it identifiable as the chloroplast.

Label D is the starch granule. The shiny semicrystalline structure of this organelle makes it identifiable as the starch granule.

Answer:

Chloroplast, Vacuole, Cell wall, Endoplasmic reticulum

Explanation:

Label A: Chloroplast

Label B: Vacuole

Label C: Cell wall

Label D: Endoplasmic reticulum

Suppose that Rosie and Ross are both carriers for PKU (a rare autosomal recessive disease.) If they have eight children, what is the probability that all of eight children will have the same phenotype?

Answers

Answer:

1/65,536 = 0.001523 %

Explanation:

A: normal allele

a: recessive allele causing PKU

The probability that Rosie and Ross have one child with PKU will be >>  

Aa x Aa = 1/4 AA; 1/2 Aa; 1/4 aa

In consequence, the probability that Rosie and Ross have eight children with PKU will be >>  

(1/4)⁸ = 1/65,536 = 0.001523 %

If Rosie and Ross are carriers of PKU, if they intend having 8 children, the probability that they will all have the same phenotype is: [tex]\mathbf{\frac{1}{65,536}; 0.001523 \%}[/tex]

Given that Rosie and Ross are both carriers of the recessive disease, it means that for the disease to manifest itself, two recessive alleles must be present in an allelic pair.

Using P and p to denote the dominant and recessive alleles respectively, we have the following gene of both parents:

Rosie - PpRoss - Pp

The cross between both parents has been provided using a Punnett square as shown in the attachment.

The cross shows that, for any cross between both parents, there is [tex]\frac{1}{4}[/tex] probability that the child would have the phenotype, pp, which means the child would have the are autosomal recessive disease.

Therefore, the probability for for 8 children having the same phenotype will be:

[tex]\frac{1}{4} \times \frac{1}{4} \times \frac{1}{4} \times \frac{1}{4} \times \frac{1}{4} \times \frac{1}{4} \times \frac{1}{4} \times \frac{1}{4} = \frac{1}{65,536}[/tex]

This is also approximately: [tex]\frac{1}{65,536} \times 100 = 0.001523 \%[/tex]

Therefore, if Rosie and Ross are carriers of PKU, if they intend having 8 children, the probability that they will all have the same phenotype is: [tex]\mathbf{\frac{1}{65,536}; 0.001523 \%}[/tex]

Jackson uses a battery operated toothbrush that is rechargeable. What happens when Jackson plugs his toothbrush into an electrical outlet to recharge it?

Answers

Answer:

Explanation:

The type of battery that Jackson's toothbrush is using is a secondary cell; this is because it can be recharged (meaning the electrochemical reactions taking place in the battery can be reversed). Batteries generally work in such a way that, while using it, electrons move from the anode of the battery to the cathode. In primary cells, this process continues until there are no electron to be transferred from the anode to the cathode and then the battery "dies" and is disposed. But in a secondary cell, just like the battery of Jackson's toothbrush, when the battery is been recharged, the electrons start moving from the cathode back to the anode; which makes electrons available again in the anode for use.

When molecules are exposed to heat, they
A
stop moving completely.
B
begin to slow down.
C
start to move faster.
D
explode.

Answers

Answer:

C

Explanation:

When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.

chemical composition of the Rough endoplasmic reticulum

Answers

Answer:

The rough endoplasmic reticulum consists of two dimensional flattened sacs formed from phospholipids and ribosomes.

Explanation:

Genes within DNA are expressed through transcription and translation of the genetic code.

The rough Er contains important machinery in gene expressions, Ribosomes embedded in a lipid membrane. These are small sub cellular organelles that carry out a specific function of protein manufacturing and modulation. They contain the translocon complex, integral to the translation process

The endoplasmic retuculum consists of folded phospholipid membrane sheets or cisternae- these are mainly two dimentional, and form flat sacs.These provide small specific environments from the cytosol in the cytoplasm- they span the entire cytoplasm.

Answer: The question is incomplete and options are not given, here are the options.

A. Atricial

B. Precocial

C. Hyperbole

D. Hyperactive.

The correct option is precocial.

Explanation:

It is precocial because it is the ability of new hatched birds with full feathers and eye open to be able to move around and find food after been hatched from the egg. It is common in birds and it is gotten from Latin word called precoccous. Some newly hatched birds can be able to mobilise around minutes after hatching and search for food while some cannot move around minutes after hatching to search for food, this type of birds are called Altricial.

Answers

Answer:

melanopsin

Explanation:

this note might help you :

The retinohypothalamic tract (RHT) is a photic neural input pathway involved in the circadian rhythms of mammals. The origin of the retinohypothalamic tract is the intrinsically photosensitive retinal ganglion cells (ipRGC), which contain the photopigment melanopsin. The axons of the ipRGCs belonging to the retinohypothalamic tract project directly, monosynaptically, to the suprachiasmatic nuclei (SCN) via the optic nerve and the optic chiasm. The suprachiasmatic nuclei receive and interpret information on environmental light, dark and day length, important in the entrainment of the "body clock". They can coordinate peripheral "clocks" and direct the pineal gland to secrete the hormone melatonin.

information about melanopsin : Melanopsin is a type of photopigment belonging to a larger family of light-sensitive retinal proteins called opsins and encoded by the gene Opn4.[5] In the mammalian retina, there are two additional categories of opsins, both involved in the formation of visual images: rhodopsin and photopsin (types I, II, and III) in the rod and cone photoreceptor cells, respectively.
