How are genes and proteins related?

Answer:

The gills actively uptake salt from the environment by the use of mitochondria-rich cells. some marine fish, like sharks, have adopted a different, efficient mechanism to conserve water, osmoregulation. they retain urea in their blood in relatively higher concentration.

Explanation:

Answer:

An organism in which the two copies of the gene are identical — that is, have the same allele — is called homozygous for that gene. An organism which has two different alleles of the gene is called heterozygous.

Answer:

The correct answer is option :  c. 10hrs: 14min: 10sec.

Explanation:

The question provides the following information to answer the question:

The P wave takes time to reach Seismic station A = 8 min:20 sec

P-wave arrived at seismic station A at : 10hrs:22min:30sec

So, the origin time of earthquake would be: 10hrs:22min:30sec - 8 min:20 sec = 10hrs: 14min: 10sec.

Thus, the correct answer is :  10hrs: 14min: 10sec.

Answer:

Photosynthesis is the synthesis of glucose from carbon dioxide and water in the presence of sunlight and chlorophyll with oxygen as a by-product it occurs in green plants,photosynthetic bacteria and some algae it is an anabolic(building) process and nearly all life depends on it it comprises many coordinated biochemical reactions that are necessary for the survival of the species it is divided into two phases 1 light reaction(Z-scheme) 2 dark reactions(Calvin cycle)

Explanation:

I hope this will help you:)

Answer:

Photosynthesis is the process through which autotrophs are bale to produce their own food. The Process is named so because photo means sun's light and synthesis means creating. It involves the Plants or other autotrophs absorbing the sun's light and also carbon dioxide released into the atmosphere by respiration. As a result of Photosynthesis, we obtain what is known as oxygen. This is, in fact, the biproduct of the process. Mainly, Photosynthesis occurs due to the presence of Chlorophyll which give leaves their green colour.

Key:

Autotrophs: Those who have the ability to produce their own food.

Biproduct: The extra result of a scientific equation.

Chlorophyll:  a green pigment, present in all green plants and in cyanobacteria, etc.

B. Directional Selection

Explanation:

By doing some research I found out what most of this means so let's do my favorite process, the process of elimination

A. Disruptive

Disruptive selection produces two or more species with two different traits nothing in the question says two different scorpions where formed one with big pinchers and another with big stingers no it just talks about them slowly forming big pinchers

C. Stabilizing

Stabilizing selection is when two species are produced with more similar traits nothing vastly different, I would consider them forming really big pinchers to be an extreme

Answer:

The main job of a kidney is to filter toxins and waste products from the blood. In dialysis, the machine takes in blood from the artery and pumps it through a semipermeable membrane. This function is similar to that of the capillaries in the kidney. They allow waste products to filter from the kidneys. The waste excretes into a bag in a manner similar to how the bladder excretes urine from the body. The clean blood pumps back into the body and is carried back to the heart via a vein.

Answer:

Your correct answer is option A. Viruses contain only RNA

Explanation:

Viruses are smaller than any bacteria. In fact, the largest virus is actually way smaller than the smallest bacterium ever. All viruses have a protein coat and a core of genetic material of either RNA or DNA. Unlike bacteria, viruses can't survive without a host. They can only reproduce by attaching themselves to the cells. In most cases, they definitely reprogram the cells to make new viruses until the cells burst and die. In other cases, they turn normal cells into malignant or cancerous cells. Also unlike bacteria, most of the viruses do indeed cause disease and they are quite specific about the cells they attack.

The correct statement that highlights the difference between viruses and bacteria is "Viruses cannot survive outside a host." The correct option is B.

Viruses are obligate intracellular parasites, meaning they require a host cell to carry out their life cycle.

They do not possess the necessary cellular machinery or metabolic processes to replicate on their own.

Viruses invade host cells and hijack their cellular machinery to reproduce.

When a virus infects a host, it injects its genetic material into the host cell.

The viral genetic material then takes control of the host cell's machinery and directs it to produce new virus particles.

Thus, the correct option is B.

Explanation:

Place two spatulas of the food sample into a test tube or 1 cm3 if the sample is liquid.

Add 2 cm3 of ethanol to the tube. Cover the end of the tube and shake the tube vigorously.

Allow the contents to settle.

Pour the liquid from the top of the mixture into a test tube half-filled with water.

Record the level of the food and whether the water is cloudy or clear.

As you can see no heat is needed

Emphysema happens when the tiny sacs in your lungs (called alveoli) are damaged. Chronic bronchitis is when the tubes that carry air to your lungs (bronchial tubes) get inflamed. Smoking is the most common cause of those conditions (and COPD).

Some people have asthma and COPD at the same time. If you have symptoms of both diseases, your doctor may call it asthma-COPD overlap syndrome.

People who smoke or breathe in pollution or chemicals at work for many years have higher chances of having COPD. That's why the condition often starts in middle age or later in life.

Asthma is sometimes caused by gene changes that are passed down through families. If one of your parents has the disease, you're more likely to have it. Symptoms often start in childhood.

Since asthma and COPD both make your airways swell, they both can cause shortness of breath,coughing, and wheezing.

One main difference is that asthma typically causes attacks of wheezing and tightness in your chest. COPD symptoms are usually more constant and can include a nasty cough.

To figure out which condition you have, your doctor will start with a physical exam and questions about your medical history. They’ll look at your nose and throat and listen to your lungs with a stethoscope. Your doctor will also want to do a test called Spirometry that checks how well your lungs work.

Answer:

1. Glucose And Oxygen.

2. Transpiration is the process by which water is lost in the form of water vapour by evaporation from the surface of leaves and other serial parts of plant .

3. A. Cooling Effect : The water keeps on evaporating from the leaf surface during transpiration . The heat required for evaporation of water is obtained from the plant itself and thus, the plant cools itself when it is hot outside.

B. Transpiration Pull : As water evaporates from the leaf surface, the roots pull up more water from the soil to make up for the water loss during transpiration .As a result, important mineral salts are also brought along with the water. These salts are necessary for the growth of the plant .

4. Leaf Tendrils : Sweet Pea

Spines : Cactus

Scale Leaves : Onion

5. Pitcher Plant, Venus FlyTrap, Blodderwort

6. Normally plants propogate with the help of seeds contained in the fruits . But some new plants may also be produced from other part of the plant such as the roots, stems, and leaves . This type of reproduction is called vegetative propogation .

The force of spring will be "3.75 N". The further explanation is given below.

Explanation:

The given values are:

Spring constant, K = 75.0 N/m

x₁ = 0.200 m

x₂ = 0.150 m

So that,

⇒ [tex]x=x_{1}-x_{2}[/tex]

⇒    [tex]=0.200-0.15[/tex]

⇒    [tex]=0.05 \ m[/tex]

Now,

Force of spring will be:

⇒  [tex]F=K\times x[/tex]

On putting the estimated values, we get

⇒      [tex]=75\times 0.05[/tex]

⇒      [tex]=3.75 \ N[/tex]

Answer:

−8.25N

Explanation:

Hooke’s law says the restorative spring force is directly proportional to the change of the spring length x on top, but is opposite in direction to the change in spring length.

Please, see the answer below.

Explanation:

The statement is inaccurate because a growing baby is not just a ball of multiplying cells that eventually grows large enough to form a baby.

After fertilization and the formation of a single-cell zygote, the zygote continues to divide to form a ball of cells. However, at some points, the cells start to differentiate to give rise to various organs that make up the baby.

Without differentiation, there is not way the dividing cells will give rise to baby. Hence, a growing baby should be rather viewed as a ball of multiplying cells that eventually differentiates to form a baby.

Answer: Embryos start as a ball-like structure of rapidly dividing cells. However, at a certain point in development, these cells diversify and bind together to form larger structures, such as tissues, organs, and, eventually, full systems.

Answer:

A DNA template is used to create an mRNA strand.

Explanation:

Transcription basically means a written or printed representation of something, if we connect that analogy to DNA, we are using the DNA as our template to write/create an mRNA strand out of it, basically transcribing the DNA.

What is the role of DNA template?

The DNA template is used by RNA polymerase to produce a strand of RNA with a nucleotide sequence that is the same as the coding strand for the production of functional RNA units and mRNA for making proteins.

How do you get mRNA from DNA?

mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II.
