Explain what happens to the incoming solar radiation on a cloudy day, and how this affects the temperature at Earth's surface.
Answer:
During the day, the earth is heated by the sun. If skies are clear, more heat reaches the earth's surface (as in the diagram below). This leads to warmer temperatures. However, if skies are cloudy, some of the sun's rays are reflected off the cloud droplets back into space.
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?
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.

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