Answer:
In moss, sperm and egg cells are produced after haploid spores are released from the sporophyte.
Explanation:
Took the test on edge
The following occurs in the life cycle of a moss but not in the life cycle of a gymnosperm: in mosses, when two haploid cells fuse, they form a diploid zygote that begins the sporophyte generation, which is in the last option.
What is the significance of the moss and the gymnosperm?In gymnosperms, both male and female reproductive structures are found on the same plant, and they have large, complex structures called cones that have reproductive structures, and the zygote begins the sporophyte generation, which is the dominant phase in the life cycle of the moss but not seen in gymnosperms.
Hence, the following occurs in the life cycle of a moss but not in the life cycle of a gymnosperm: in mosses, when two haploid cells fuse, they form a diploid zygote that begins the sporophyte generation, which is in the last option.

which of the following reactions provides the chemical energy for most cell functions?
a. ATP - P --- ADP
b. ATP + P --- ADP
c. ADP - P --- ATP
b. AFP + P --- ATP
Answer:
ATP - P ADP
Explanation:
Here is your answer! ^-^
ATP - P --- ADP provides the chemical energy for most cell functions.
What do you mean by chemical energy ?The bonds of chemical molecules contain energy. Exothermic reactions are those in which chemical energy is released during the reaction, frequently in the form of heat.
The energy in meals is transformed into energy that the body's cells can utilise during cellular respiration.
A new substance may form and energy may be released when the molecules of chemical substances react chemically.
Energy is transferred to ATP during cellular respiration, which transforms glucose and oxygen into carbon dioxide and water.

Which bonds could a single carbon atom have?
Choose the correct answer.
2 triple bonds
5 single bonds
a triple bond and a single bond
a triple bond and a double bond
A triple bond and a single bond is the bond which a single carbon atom can have and is denoted as option C.
What is Bond?This is referred to as the attraction which exists between atoms and are involved in the formation of substances in a chemical reaction.
Carbon on the other hand is am element with an atomic number of 6 and has four valence electrons present in its outermost shell. This means it needs four electrons to achieve a stable configuration which is why a single atom must have a total of four bonds which is a triple bond and a single bond, two double bonds etc.

All living things are made of one or more cells, and those cells are either eukaryotic or prokaryotic. You, like all animals as well as plants and fungi, have eukaryotic cells. That means your cells have a nucleus. Inside that nucleus, genetic material (DNA) is coiled into thread-like chromosomes. Organisms with eukaryotic cells are called eukaryotes. Prokaryotic cells, on the other hand, are more simple. They lack specialized, membrane-bound organelles, like mitochondria, and they do not have a nucleus. Their genetic material is usually in a loop that floats in the cytoplasm. That loop is called the nucleoid. Prokaryotic cells are much smaller than eukaryotic cells. All bacteria are unicellular, made of just one cell, and they are prokaryotes. Some bacteria have flagella, tail-like structures on the end that help them to move.
How are bacteria cells different from human cells?
A
Bacteria cells do not contain a cytoplasm.
B
Bacteria cells do not contain genetic material.
C
Bacteria cells are much bigger than human cells.
D
Bacteria cells are less complex than human cells.

Aquifers are underground layers of rock that can hold water. Freshwater is pumped out of aquifers for many household uses. However, withdrawing too much water from aquifers drains them and makes the ground more likely to collapse. One way to reduce the amount of wate withdrawn from aquifers is to reduce the amount of water used in homes.
a. Describe a method or device that could be used to monitor the amount of water being used in the home.
b. Describe one way people can reduce their daily use of water and explain how the change can create a larger, positive impact in the community.
Online water monitoring
New York City was the first major city in the world to offer online water tracking, as part of the city’s shift to the equivalent of a smart grid for water.
Utility officials have traditionally read water meters manually, sometimes as infrequently as four times per year. Of course, sending out meter readers is expensive and inefficient. It also means water bills may be based on estimates and subject to human error.

Answer:
Germ
Explanation:

The types of cells which are found n the reproductive organs of humans are known as germ cells.
Which types of cell divisions are performed by germ cells?The types of cell divisions that are performed by germ cells are known as meiosis and mitosis. Meiosis is a type of cell division through which produces four haploid daughter cells that are not identical to their parents.
Germ cells are responsible for the production of gametes. This involves the differentiation of germ cells in order to produce male and female gametes. These cells are sometimes known as immortal because they are thought be assemble a linkage between generations.
Somatic cells are those cells that are responsible for the building blocks of the entire body. These somatic cells are only divided by mitosis.
Therefore, germ cells are the types of cells that are found in the reproductive organs.

what happens to the concentration of oestrogen at ovulation?
Answer:
When oestrogen rises to a high enough level it causes a surge in LH from the pituitary which causes ovulation where an egg is released from the follicle (Day 14 of the cycle). The follicle becomes the corpus luteum and this produces oestrogen and progesterone which inhibit FSH and LH production by the pituitary.
