Animal and plant cells have all of the following EXCEPT
A. chloroplasts to carry out photosynthesis.
B. vacuoles to store water and nutrients.
C. a nucleus with DNA to replicate cells.
D. mitochondria to form chemical energy.
Answer:
The answer is A, chloroplasts to carry out photosynthesis.
Explanation: The animal cell does not have photosynthesis.
Animal and plant cells have all of the following EXCEPT - A. chloroplasts to carry out photosynthesis.
Chloroplasts are the cellular membrane-bound organelle that is specific to the plant cell and does not found in animal cells. Chloroplast carried out the process known as photosynthesis.
In these organelles, photosynthetic pigment chlorophyll found that captures the energy from sunlightMitochondria are also membrane-bound organelle found in all eukaryotic cells including animal and plant cells to carry out cellular respiration.The nucleus is also present in both types of the eukaryotic cell, plant and animal cell that stores genetic material.Vacuoles are present in the eukaryotic cells, to store water and nutrients.Thus, Animal and plant cells have all of the above EXCEPT - A. chloroplasts to carry out photosynthesis.

If the DNA integrates properly into the germ cells, the adult fly will contain _________________ that contain _____________________________. After mating, these flies can then produce progeny that will contain ______________________.
Answer:
Five pairs of autosomal and one pair of heterochromatic sex chromosomes.
Explanation:
The adult fly will contain 12 number of chromosomes that contain five pairs of autosomal and one pair of heterochromatic sex chromosomes. After mating, these flies can then produce progeny that will contain diploid i. e. double number of chromosome. One set of half chromosomes from the male fly while the other half chromosomes comes from female fly so the offspring will receive double number of chromosomes.

A student is performing an investigation using rennin and milk. Rennin is an enzyme that can solidify milk. She
puts milk in three test tubes with rennin and places the tests tubes in water baths at different temperatures
of 32°F, 98°F, and 212°F. She notices the rennin enzymes become denatured at 212°F and do not solidify
the milk. Which statement correctly describes the effect of the denatured enzymes?
A. Denatured enzymes are slowly active.
B. Denatured enzymes are no longer active
C. Denatured enzymes reverse the reaction.
D. Denatured enzymes speed up the reaction.
Answer:
The correct answer is - option B. denatured enzymes are no longer active.
Explanation:
Denaturation of the enzymes or proteins results in changes in their original structure which ultimately results in the loss of their particular functions. The denaturation of proteins or enzymes takes place due to extreme temperature or pH which leads to a change in the active site of an enzyme.
Due to this change, the substrate will no longer fit in the active site and become inactive as enzymes work together with the substrate and the active site is the essential part of the enzyme for its activity. In this case, this is condition takes place which makes it denatured at 212 degrees F.

Margo notices that waves start passing her more often. What can she conclude about the frequency and wavelength of the waves?
Maro concluded that the frequency is increased while the wavelength would be decreased with respect to the wave that starts passing her more often.
What is Wavelength?Wavelength may be characterized as the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire.
The frequency or the energy of the wave is inversely related to the wavelength of any wave. This is because when frequency increases, wavelength (λ) decreases, and vice-versa. While the energy of the wave and frequency is directly related to one another.
Therefore, Maro concluded that the frequency is increased while the wavelength would be decreased with respect to the wave that starts passing her more often.

Luster refers to the way that an object, such as a mineral, reflects light. The luster may be metallic or nonmetallic. A
mineral with a metallic luster may look golden or silver. A mineral with a nonmetallic luster may look adamantine
(transparent and sparkly like a diamond), pearly, vitreous (glassy), waxy, silky, resinous (like honey), or greasy. Nonmetallic
minerals with little or no luster tend to have an earthy, dull look.
Examine all the mineral samples in your kit one by one to determine if they have a metallic or a nonmetallic luster. Some
minerals may be only partially lustrous. Hold them up to the light and look on all sides for an accurate observation.
Classify each mineral as metallic or nonmetallic in the table.

genetics and the environment both play roles in cell differentiation. which is the best example of an environmental factor influencing cell differentiation
Answer: etiolation of plant growth in shade, with fast growing cell without chloroplasts. Out of shade, cell differentiate again to produce photosynthesising cells
Explanation: It is a subjective decision as to what is ‘best’. Good examples are plant responses to changes in the nutrient supply.
when soil nitrogen is depleted some plants, such as legumes, grow nodules on their roots, with cells that release chemical signals to attract nitogen fixing bacteria.
Lack of light induces etiolation in many plants. New cells elongate and develop without chloroplasts, with rapid cell division exhibiting gravitropism, extending upward. When they grow beyond the shade area, cell differentiation changes again, to produce photosynthesising cells.
