Answer: (1) It has a tail to travel to the egg (2) contains a nucleus in the head which will fertilise the egg
Explanation: Firstly it has a tail to help it travel to the egg. Secondly it contains the nucleus in the head that will fertilise the egg. Thirdly the acrosome contains enzymes in order for the sperm to penetrate the egg. Finally, the sperm cell is packed with mitochondria to provide the energy needed to reach the egg.
Sperm cells are highly specialized for the purpose of fertilization. Here are two ways in which sperm cells are adapted for this process: Streamlined shape, Acrosome, and enzymes.
1. Streamlined shape: Sperm cells have a streamlined shape, often described as being tadpole-like, with a long and slender tail (flagellum) and a compact head region.
This shape is adapted for efficient swimming through the female reproductive tract to reach the egg. The flagellum allows the sperm to propel itself with whip-like movements, providing mobility and the ability to navigate through the female reproductive system.
The streamlined shape reduces drag and enables the sperm to move swiftly towards the egg, increasing the chances of successful fertilization.
2. Acrosome and enzymes: The head region of a sperm cell contains a specialized structure called the acrosome. The acrosome is a cap-like structure that covers the front portion of the sperm's head.
Inside the acrosome, there are enzymes, such as hyaluronidase and acrosin, which play a crucial role in fertilization.
When the sperm reaches the vicinity of the egg, the enzymes are released and help the sperm penetrate through the protective layers surrounding the egg, such as the zona pellucida.
Thus, the streamlined shape and the presence of the acrosome with enzymes are two important adaptations of sperm cells that increase their chances of successful fertilization by facilitating efficient swimming and penetration of the egg's protective layers.

GIVING BRAINLY! A car started accelerating and it gained speed at 2 m/s2. The car had a mass of 200 kilograms; calculate the average force the car was traveling at.
Answer: ____ Newtons
Answer:
100 Newtons
Explanation:
The car was traveling at an average force of 400 Newtons. This is the force that was being applied to the car to cause it to accelerate at a rate of 2 meters per second squared.
What is force?In physics, force is a measure of the interaction between two objects that can cause a change in the motion of one or both objects. Forces can be classified as either contact forces, which involve physical contact between two objects, or non-contact forces, which involve the interaction of objects without physical contact.
To calculate the average force that the car was traveling at, you can use the equation for average force:
average force = mass x acceleration
Plugging in the values given, you get:
average force = 200 kg x 2 m/s2 = 400 N

When the sun's energy reaches the Earth, some is reflected into space, but the rest is absorbed by gases and warms the atmosphere. This phenomenon is known as
- climate change
- global warming
- greenhouse effect
- positive feedback
Answer:
Greenhouse effect
Explanation:
When the sun's energy reaches the Earth, some is reflected into space, but the rest is absorbed by gases and warms the atmosphere; this phenomenon is known as the "greenhouse effect," which is present in the third option.
What is the greenhouse effect?When solar energy strikes the earth, some of it is reflected back and some is trapped in the atmosphere's gaseous layer, such as carbon dioxide; water vapor traps this radiation and warms the earth. Global warming is seen as having serious consequences due to its warming nature, including the melting of the polar ice, agricultural destruction, and so on.
Hence, when the sun's energy reaches the Earth, some is reflected into space, but the rest is absorbed by gases and warms the atmosphere; this phenomenon is known as the "greenhouse effect," which is present in the third option.

A cell has a mutation that disrupts the insulin binding site of the insulin receptor. Based on the information in Figure 2, predict the effect of this mutation on the activity of GSK3. Justify your prediction.
Answer:
See Explanation
Explanation
If insulin cannot bind to the insulin receptor, then GSK3 will not be inhibited, nor will it be able to inhibit glycogen synthase as the activity of kinases such as PKB and GSK3 are dependent on the signal sent out as the response of binding insulin to the receptor. No binding leads to no signal which leads to no activity.

show that respiratory gaseous exchange in a rabbit occurs at the level of lungs
No single animal model can reproduce all of the human features of both acute and chronic lung diseases. However, the rabbit is a reliable model and clinically relevant facsimile of human disease. The similarities between rabbits and humans in terms of airway anatomy and responses to inflammatory mediators highlight the value of this species in the investigation of lung disease pathophysiology and in the development of therapeutic agents. The inflammatory responses shown by the rabbit model, especially in the case of asthma, are comparable with those that occur in humans. The allergic rabbit model has been used extensively in drug screening tests, and this model and humans appear to be sensitive to similar drugs. In addition, recent studies have shown that the rabbit serves as a good platform for cell delivery for the purpose of stem-cell-based therapy.
