What happens during the lytic cycle of a viral infection?
Answers
2) The DNA circularises
3) Viral gene activates the host cell's DNA synthetic machinery
4) Rapid reproduction of viral DNA occurs
5) Host makes viral capsomeres, allowing viral assembly to take place
6) Due to the large volume of new bacteriophages inside the host cell, the cell splits (cell lysis), releasing the new bacteriophages

If the 2° consumers have 467 kcal, how much energy did the producers have?
Thank you to any answers!
Answers
a) 23.4 Kcal is the energy will the 3° consumers receive.
b) 46700 Kcal is the energy producers have.
Explanation:
The energy value is given for the trophic levels. There is a 10 % rule of energy transfer which is applicable to the producers and consumers in the energy pyramid. According to it 10 % energy is transmitted to upper level in a pyramid while 90% gets dissipated in the form of heat.
Energy of producer = 23400 kCal
energy transferred to tertiary consumer = ?
At first the energy transferred to primary consumer is calculated as:
10 % of 23400 Kcal
x 23400
energy transferred to primary consumer = 2340 Kcal
energy transferred to secondary consumer:
10% of primary consumer energy
x 2340
= 234 Kcal
energy transferred to tertiary consumer:
10% of energy of secondary consumer
x 234
= 23.4 Kcal
Tertiary consumer will recieve 234 Kcal of energy.
b) Energy of secondary consumer is 467 Kcal
energy of producers =?
energy of producer was 100 times the energy of secondary consumer
467 x 100
= 46700 Kcal.

Answers
Unlike photosynthesis, cellular respiration occurs in all the eukaryotic cells. Thus, the correct option is D.
What is Cellular respiration?
Cellular respiration is the process by which the biological fuels such as carbohydrates (glucose sugar) are oxidized in the presence of an inorganic electron acceptor such as oxygen to produce large amounts of energy-rich compounds, to drive the bulk production of ATP molecule. This process occurs in all types of eukaryotic cells including plant cells and animal cells.
Photosynthesis is the process of formation of food in the form of carbohydrate (glucose) in the presence of sunlight and carbon dioxide in the chloroplast of plant cell and organisms which contain a chloroplast.
Therefore, the correct option is D.

Answer;
B. 40°
m∠BAC = 40°
Explanation;
- In the question AC is the diameter of the circle.
- ACB is a triangle with angles m∠BAC, m∠ACB and m∠ABC.
- Angles subtended by a diameter to the circumference of a circle is always right angle or 90 degrees.
- Therefore, angle m∠ABC, which is subtended by diameter AC to the circumference is 90 degrees.
But, angles in a triangle adds up to 180 degrees, therefore;
m∠BAC = 180 - (m∠ACB + m∠ABC)
= 180 - (50 + 90)
= 180 - 140
= 40°
Thus; m∠BAC = 40°
The solution of m∠BAC is mathematically given as
m∠BAC = 40°. This is further explained below.
What is angle
The angle formed by two crossing lines or surfaces, commonly expressed as a number of degrees.
What is the solution of m∠BAC?
Generally, the equation for angle m∠BAC is mathematically given as
m∠BAC = 180 - (m∠ACB + m∠ABC)
m∠BAC = 180 - (50 + 90)
m∠BAC = 40°
In conclusion, m∠BAC = 40°

Animals that live in taiga biomes had to adapt to seasonal changes, by changing their fur or feather color. For example, snowshoe rabbit and arctic fox live in taiga and their fur color changes with environmental conditions. To effectively camouflage, their fur is white during the winter. That helps them blend into the snow. In the summer, where there is no snow, their fur is brown and similar to the soil color. This way they evade predators because it is more difficult for their predators to spot them.
Answer:
A) Climate
The arctic fox and snowshoe rabbit have made species adaptations over time that help them to survive. For example, both creatures have fur that turns white in winter. They also have fur on the pads of their feet. These are both examples of their adaptations to Climate
