<h2>Answer:</h2>

Lysosomes are organelles that contain digestive enzymes (acid hydrolases). They digest excess or worn out organelles, food particles, and engulfed viruses or bacteria. The membrane surrounding a lysosome prevents the digestive enzymes inside from destroying the cell.

As it turns out, our tears do contain some magic, namely the powerful enzyme lysozyme. This enzyme is crucial in thwarting bacteria that attempts to enter our body cavities. By destroying the peptidoglycan layer of bacterial cell walls, it serves as a strong chemical defense against bacterial infections.

From point W to point Z, the ball is B- Potential energy was transformed to kinetic energy. We know this because, at point W, the ball is in its potential form, it has the potential to roll but it has not yet started to. As we let the ball go, we turn that potential energy into kinetic energy, which is the energy that it has due to its motion.

Clark's eyes are blue in color. However, both his parents have eyes that are brown in color. According to the dominant-recessive

Zepler [3.9K]

Answer:

Both parents are heterozygous for the trait. They must be carriers of the recessive gene that codes for blue eyes.

Explanation:

Let us assume that the dominant gene codes for brown eyes while the recessive gene codes for blue eyes. We can suggest that both parents are carriers of the recessive gene. They both express brown eyes because they also have a dominant gene that codes for brown. Clark inherited one recessive allele from each parent, so he expresses blue eyes. The couple has a 75% probability of getting a brown-eyed child, while the probability of getting a blue-eyed child is 25%.

c. 2400 calories per day for each of them

d. 2000 calories per day for each of them

The answer is option B -2200 calories per day for Zondra and 3000 per day for Austin

Calories provide energy which we use to perform daily activities. The calories derived from food allow us take part in important activities and leisure. Calorie needs are often higher during teenage years because it is the time of rapid growth.

Austin, is her 16 year old son. The recommended calorie needs for adolescent males between the ages of 16- 18 are; 2,400 calories for non active adolescents, 2,800 calories for moderately active adolescents and 3200 calories for active adolescents.

Zondra is a 14 year old female adolescents. The recommended needs for adolescent females between the ages of 14-18 are; 1,800 calories for non active adolescent females, 2,000 calories for moderately active and 2,400 calories for active adolescent females.

Option B, 2200 calories per day for Zondra and 3000 per day for Austin fall within the range

A bactericidal antibiotic, such as penicillin, kills the bacteria. These drugs usually interfere with either the formation of the bacterial cell wall or its cell contents. A bacteriostatic stops bacteria from multiplying.
