strobila or cone produce egg cell in non flowering plants
The organ in many nonflowering plants which produces an egg cell is the strobila or cone produce.
What is nonflowering plants?Nonflowering plants don't produce flowers; instead, they produce microscopic reproductive elements called seeds or spores that may be used to create additional plants that look just like them.
What is strobila?A shorter stem with several altered leaves bearing sporangia makes up strobili. Gymnosperms, like all seed plants, are heterosporous. Usually, different cones are used to carry the sporangia that produce the male microspores as well as female megaspores.
Nonflowering plants like ferns, mosses, etc other nonflowering plants have reproductive organs called antheridium and archegonium. The male gametophyte's primary source of sperm cells would be the antheridium (male gametes). Numerous sperm will be produced by the antheridium for fertilization.
Therefore, The organ in many nonflowering plants which produces an egg cell is the strobila or cone produce.

Scientists claim that increased demand for almonds would have a negative environmental impact on California. Which observation, if any, would support this claim?
A. The almonds are exported to other states and countries and profits increase for California's almond industry.
B. The increased demand for almonds increases the freshwater consumption in California.
C. The additional CO₂ produced by the almond trees is released into the atmosphere.
D. The additional consumption of sunlight by the almond trees reduces the amount of energy input on the solar panels and therefore the amount of energy available to Californians.
Answer:
The main issues associated with almond milk production are water use and pesticide use, which may produce long lasting effects on the environment in drought-stricken California, where more than 80% of the world's almonds are grown

C. They are the daughter cells that form during cell replication.
D. They are part of the lined-up chromosomes in mitosis.
Answer:
D
Explanation:
they are part of the lined-up chromosomes in mitosis
i just took the quick check
In conclusion, the statement 'they are part of the lined-up chromosomes in mitosis' CORRECTLY describes sister chromatids (Option D).
During the synthesis (S) phase of the cell cycle, each chromosome is replicated. These identical DNA molecules are called sister chromatids.In mitosis, sister chromatids are held together and line up at the equator plate of the cell during metaphase.During anaphase, sister chromatids (now called chromosomes) are separated and pulled towards opposite poles of the cell by the mitotic spindle.In conclusion, the statement 'they are part of the lined-up chromosomes in mitosis' CORRECTLY describes sister chromatids (Option D).

Glucose molecules bond together in a process known as dehydration synthesis. What
happens in this process?
The reaction uses water molecules to break the bonds in each glucose.
O4 water molecules are lost from each bond broken
O 4 Water molecules are used for every
O 1 water molecule is lost (OH + H) for every bond formed
Glucose molecules bond together in a process known as dehydration synthesis, and in this process, 1 water molecule is lost (OH + H) for every bond formed. The last option is correcting the glucose dehydration reaction.
What is glucose dehydration?The macromolecules, such as the polysaccharides and proteins, are formed by the dehydration reaction, and in this reaction, the water is lost to make the polymer. The single glucose molecules unite with each other and release a single unit of water to form the polymers, and in this way the polymers such as glycogen, starch, and cellulose are formed.
In the case of proteins, each amino acid dehydrates and releases one molecule of water, forming the polypeptide chain. As a result of the dehydration process, the monomers combine to form the polymer, which can be structural or functional.
Hence, for every bond formed, one water molecule (OH+H) is lost. The last option is correct regarding the glucose dehydration reaction.

Which characteristic best explains why lentic ecosystems are more responsive to seasonal changes than lotic ecosystems?
Photosynthetic organisms keep lentic ecosystems warmer during the winter season.
Lentic ecosystems are susceptible to temperature due to their low dissolved oxygen.
Lotic ecosystems have low nutrient levels, making them more sensitive to temperature.
Lentic ecosystems tend to have smaller volumes of water compared to lotic ecosystems.
Lentic ecosystems tend to have smaller volumes of water compared to Lotic ecosystems.
Lentic ecosystem consists of still (stagnant) volume of water and good examples include ponds,lakes, basins etc.
Lotic ecosystem , on the other hand consists of a flowing volume of water and examples include seas, oceans, rivers etc.
The Lentic ecosystem usually is usually still and is affected by seasonal changes as it contains smaller volume of water when compared to the Lotic ecosystem which has a high volume.
Seasonal changes such as summer or winter affects the Lentic system easily as the small volume of water gets heated up and frozen easily which encourages more evaporation and freezing respectively.

How does an atom become a positive ion?
O A. It loses an electron.
O B. It gains a neutron.
O C. It gains an electron.
D. It loses a neutron.
Answer:
The answer is C
Explanation:
Mark the brainly
Answer:
A. It loses an electron
Explanation:
An atom becomes a positive ion when it loses an electron (then there are more protons than electrons in the atom) when it is trying to reach stability. This is called a Cation. The opposite of this is an Anion, when an atom gains an electron to reach stability and becomes a negative ion (because the number of electrons are higher than the number of protons).

A student placed 20 ml of different sweet drinks in seven identical flasks She then added 5 grams of yeast to each flask Each flask was then covered with identical balloons as shown below
Balloon size increases as the sugar increases in the solution.
As the yeast feeds on the sugar or sugar solution which produces carbon dioxide gas. Due to presence of balloon, there is no place to go so gas slowly fills the balloon. Carbon dioxide gas produces from yeast fills thousands of balloon.
That solution which have high amount of sugar in it will leads to higher concentration of carbondioxide gas in the balloon so we can conclude that balloon size increases as the sugar solution increases.
