Answer:

Valine-Leucine-Proline-Lysine-Histidine

Explanation:

The central dogma of biology is the process by which DNA is used to synthesize RNA and subsequently amino acid sequence (PROTEIN). The processes of transcription and translation is used in gene expression. Transcription is the process whereby the information encoded in a DNA molecule is used to synthesize a mRNA molecule. Transcription is catalyzed by RNA polymerase enzyme, which uses complementary base pairing rule i.e Adenine(A)-Thymine(T), Guanine(G)-Cytosine(C) pairing.

N.B: Thymine is replaced by Uracil in the mRNA

For the above DNA sequence: CAC GAC GGA TTC GTA, the mRNA sequence will be: GUG CUG CCU AAG CAU

Translation is the second process of gene expression which involves the synthesis of an amino acid sequence from an mRNA molecule. The mRNA is read in a group of three nucleotides called CODON. Each codon specifies an amino acid (see attached image for genetic code)

Based on the attached genetic code, an mRNA sequence: GUG CUG CCU AAG CAU will encode an amino acid sequence: Valine(Val) - Leucine (Leu) -Proline (Pro) -Lysine (Lys) - Histidine (His).

GUG specifies Valine amino acid

CUG specifies Leucine amino acid

CCU specifies Proline amino acid

AAG specifies Lysine amino acid

CAU specifies Histidine amino acid

Draw three different food chains, from this food web, that contain an aphid.
serg [7]

The food chain that would include an aphid include:

  • Plant ---> Aphid ----> Birds
  • Plant ---> Aphid ----> Spiders
  • Plant ---> Aphid ----> Bat

<h3>What is a food chain?</h3>

A food chain is a chart that shows how food is transferred from producers to consumers.

Producers are plants as they are responsible for producing food from inorganic materials using the Sun's energy.

Consumers depend on plants and other organisms.

The food chain that would include an aphid include:

  • Plant ---> Aphid ----> Birds
  • Plant ---> Aphid ----> Spiders
  • Plant ---> Aphid ----> Bat

If you had to pick a specific food that was high in potential energy to include in your diet, which food would you pick and
torisob [31]

Answer:

I would choose a food source that has a significant level of carbohydrates, proteins, and vitamins. <em>E.g.</em> bananas.

Explanation:

Food is one of the most important ways to increase our energy. It may be very common to feel lethargic throughout the day when one's diet is not appropriate or balanced.

According to nutriologists, bananas are one of the best foods that boost our energy. Bananas contain carbohydrates, [natural] sugar, minerals, and amino acids. Incorporating this fruit into your diet can be extremely helpful, especially if you practice sports. In fact, recent research showed that consuming bananas before and after exercising helps you maintain your body with high levels of energy throughout the day and, therefore, helps you to have a better performance.

Match the givin changes in the ecosystem to their causes
poizon [28]

Answer:

The correct answers are:

1. Greenhouse gases: Earth's heat is kept from going away.

Greenhouse gases, particularly CO2 and methane, have properties that allow them to trap heat in the atmosphere. This means that the more of these gases there are in the air, it will be hotter on Earth.

2. Chemicals released into the river—unfit for human consumption.

The chemicals released into rivers pollute the water, making it unfit for human consumption. There are only a few places in the world where there is enough freshwater to go around, so the fact that so many rivers have been poisoned is very worrying.

3. Excessive agricultural land use—forest fragmentation.

People cut down the trees so that there is more land that can be used for farming, As a result of this process, forests are being destroyed to the point of total devastation, and it is likely that this percentage will rise in the coming years as things continue.

The suprachiasmatic nuclei enable the nervous system to respond to daily light/dark alterations through their stimulation of
timama [110]

Answer:

The suprachiasmatic nuclei enable the nervous system to respond to daily light/dark alterations through their stimulation of melatonin.

Explanation:

Melatonin is a hormone produced naturally by the body. Its function is to regulate the body's circadian cycle. This hormone is stimulated and begins to act by changing between a light environment and a dark environment. This stimulation interacts with the suprachiasmatic nuclei making the nervous system understand this change and luminosity of the environment and respond to the action of melatonin.
