use the drop-down menu to answer the question.

what property is the mineral in this image demonstrating?
a. magnetism
b. fluorescence
c. luster
d. streak

help me asap. pls.

Answers

The answer would be b. Fluorescence

When a particular wavelength of light, such as ultraviolet (UV) light, electron beams, or x-rays, are focused on a mineral, fluorescence takes place, hence option B is correct.

What is the property of minerals?

Calcite, fluorite, and sodalite are among the more popular fluorescent minerals, however there are many more as well. When exposed to UV light, many gemstones, including diamonds, rubies, emeralds, amber, and opal, will glow

This light stimulates the mineral's electrons, forcing them to momentarily move to a higher orbit.

Naturally, mine wastes and tailing heaps provide excellent locations for any mineral, including fluorescents.

Therefore, nearly everywhere that has a good assortment of white light minerals also has fluorescent minerals, hence option B is correct.

What are the different types of leaves that plants have?

Answers

Answer:

There are two different types of leaves – simples leaves and compound leaves. The other types of leaves include acicular, linear, lanceolate, orbicular, elliptical, oblique, centric cordate, etc. They perform the function of photosynthesis and help in the removal of excess water from the aerial parts of the plant. The most obvious aspect to examine is the shape of the leaf. If it is an uninterrupted shape, it is simple. If the shape divides into smaller leaf sets the leaf is compound. Identifying plant leaves that are compound divides them into subsets.

I'm so confused anybody can help?​

Answers

Answer:

Photosynthesis vs Cellular Respiration

Uses water <=> Gives off water

Uses carbon dioxide <=> Gives off carbon dioxide

Makes Glucose <=> Breaks down glucose

Gives off oxygen <=> Uses oxygen

Occurs only in light <=> Occurs all the time; does not need light

Takes in light energy <=> Releases light energy stored in glucose

Explanation:

Photosynthesis and Cellular Respiration are both biological processes. One is the reverse of the other.

Photosynthesis is an anabolic process while cellular respiration is a catabolic process. It implies that photosynthesis synthesis food by capturing energy while cellular respiration breaks down food and releases energy for cellular activities.

The two processes are important to keep each other going.

Plants release oxygen which is a by-product of photosynthesis, and we breathe in oxygen so that our cells can carry out cellular respiration and generate ATP.

Photosynthesis uses light energy, carbon dioxide and gives off glucose, water, and oxygen as by-product while cellular respiration uses water and glucose, and gives off carbon dioxide, water and energy as by-products.

While photosynthesis occur in green plants in the presence of light, cellular respiration occurs at all times.

Which statement best explains why a plant cell has chloroplasts but most animal
cells do not?

Answers

Answer:

Both animal and plant cells have mitochondria, but only plant cells have chloroplasts. Plants don't get their sugar from eating food, so they need to make sugar from sunlight. Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria.

Explanation:

A plant cell needs to make food out of chloroplasts using energy from the sun to get its food, while the animal cell eats food and creates energy, which is the reason why animal cells do not need chloroplasts.

Explanation:

If a sperm containing 46 chromosomes fused with an egg
containing 46 chromosomes, how many chromosomes would
the resulting fertilized egg contain?
Do you think this would create any problems in the developing
embryo?

Answers

Answer:

Explanation: yes would cause problems with the embryo because a sperm and egg have 23 chromosomes each half mom half dad.

The sperm cell and the egg cell contain 46 chromosomes each, 46 + 46 = 92; a developing embryo would not survive if it contained 92 chromosomes.

What is fertilization?

This process results in the restoration of the diploid state, the formation of a zygote through the process of egg activation, and the beginning of a series of mitotic divisions that leads to cell differentiation and embryo development.

When a sperm and a female act during sexual contact, an egg is created and implanted in the female's uterus, resulting in fertilization. The sperm enters the fallopian tube, passes through the ovum's zona pellucida layer, and fuses with the egg to create the zygote (fertilized egg).

Therefore, 46 chromosomes are found in each sperm and egg cell, for a total of 92 chromosomes. An embryo would not survive if it had 92 chromosomes.
