Answer:
- These are water bodies formed from melting glaciers
- However, their size can vary from a few square meters to thousands of square kilometers
- They can be seasonal, existing for a few months or exist for hundreds of years or more
Explanation:
The lakes and the ponds are freshwater bodies of water. They can be formed in numerous different ways, from melting of glaciers, rivers flowing into closed valleys, changes in the geography of a space, increased amounts of precipitation. They can vary in size, and there are ponds and lakes that are very small, just few square meters, or to be thousands of square kilometers in size. Some of the lakes and ponds tend to be seasonal, unlike the majority that are existing throughout the whole year, and the reasons for this are the climate and the manner in which they form. Some lakes can be very old, millions of years of age, like the Ohrid Lake in Macedonia, which is also the most important lake in the world from biogeographical stance of point, and it is considered as one of the most attractive ones in the world as well.

Guard cells control which event?
the growth of plants
capture of solar energy
gas exchange in leaves
water absorption in roots
Guard cells control the massive amounts of gaseous exchange that takes place through the small pores known as stomata. Thus, the correct option for this question is C.
What are Guard cells?Guard cells may be defined as the kidney-shaped cells that envelop the stomata and are responsible for opening and closing of the stomatal pore.
A large amount of water is lost as a result of the opening of stomata for a long time, so the plant closes these pores when they do not need carbon dioxide for photosynthesis.
The guard cells swell when water flows into them, causing the stomatal pore to open, while the guard cell shrinks when water flows away from them, causing the stomatal pore to close.
Therefore, Guard cells control the massive amounts of gaseous exchange that takes place through the small pores known as stomata. Thus, the correct option for this question is C.

Explanation:
The rock cycle contains these processes. The rock cycle depicts how rocks can change from one type of rock to the other. They do not necessarily have to follow a specific order, but these process aid in transforming one rock to another type of rock.
For example, an igneous rock can tuen into sedimentary rocks through weathering and erosion first. When the rock is broken down into pieces called sediments, , these sediments settle through the process of sedimentation. If enough sediment accumulates, it eventually forms a sedimentary rock. If the same rock eventually is subjected to immense heat and pressure, the process of metamorphism can occur, which turns it into a metamorphic rock.

What happens when a Chlorine atom gains an electron its outer energy shell
Answer:
It becomes an ion, specifically an ANION.
Explanation:
A stable Chlorine atom would be neutral, or it would have no charge. This means that there is an equal number of electrons and protons (17 to be specific).
When a stable atoms gains or loses an electron, it's charge will not be neutral anymore because there would either be more electrons, than protons; or more protons than electrons.
In the case of your problem, there would be more electrons, so when electrons outnumber the protons, then the atom becomes negatively charged. A negatively charged ion is called an ANION.
Neutral ANION

3. Most animals and plants reproduce sexually. This means that DNA is passed down to new organisms from two parental organisms
Which of the following is a key advantage of sexual reproduction?
A. Increased genetic diversity for changing environments
B. The creation of new genes to improve survival
C. The receipt of the strongest genes from both parents for survival
D. The elimination of genetic mutations from a parent organism
Answer:
The correct option is A.
Explanation:
There are two basic types of reproduction, they are asexual and sexual reproduction. Asexual reproduction involves the division of a mature organism into two different organisms through binary fission or other forms of asexual reproduction. In this case the offspring is similar both physically and genetically to the parent organism. There is no genetic diversity in this case and the same disease can easily wipe out the entire population of the organism.
Sexual reproduction on the other hand requires two different organisms. During the reproductive process the genetic materials from the two organisms get mixed up thoroughly, so they end up giving birth to offspring that are quite different from them genetically.
The diversity in genetics makes it possible for the offspring to cope with changing environmental conditions. Because, the offspring are diverse in constitution, some offspring will always be able to survive harsh environmental conditions due to their genetic make up.
Answer:
The Option A is correct i.e.
Sexual organisms increases genetic diversity for changing environments
Explanation:
Reproduction is the biological process by which new organisms are produced from their parents.
In asexual reproduction, an organism can reproduce without the involvement of another organism. By asexual reproduction, an organism creates a genetically similar or identical copy of itself.
Sexual reproduction typically requires the sexual interaction of two specialized organisms, called gametes, which contain half the number of chromosomes of normal cells and are created by meiosis, with typically a male fertilizing a female of the same species to create a fertilized zygote. This produces offspring organisms whose genetic characteristics are derived from those of the two parental organisms.
The diversity in genetics makes it possible for the offspring to cope with changing environmental conditions. Because, the offspring are diverse in constitution, some offspring will always be able to survive harsh environmental conditions due to their genetic make up.

In general, are there any major differences that you can see? Explain
Prokaryotes lack a true nucleus, membrane-bound organelles, and are typically single-celled.
Eukaryotes have a nucleus, organelles, and can be single-celled or multicellular.
Nucleus: One of the most fundamental distinctions is the presence of a true nucleus. Prokaryotes, including bacteria and archaea, lack a membrane-bound nucleus.
Membrane-Bound Organelles: Eukaryotic cells contain various membrane-bound organelles, such as the endoplasmic reticulum, Golgi apparatus, mitochondria, and chloroplasts (in plants). Prokaryotes have very few organelles and typically lack these membrane-bound structures.
Cell Size: Prokaryotic cells are generally smaller and simpler than eukaryotic cells, which can be much larger and more complex.
Cell Division: Prokaryotes usually reproduce asexually through binary fission, while eukaryotes have more complex modes of cell division, including mitosis and meiosis.
Genetic Material: In prokaryotes, the genetic material is typically a single circular DNA molecule. Eukaryotes have multiple linear DNA molecules.
Ribosomes: Ribosomes are the cellular structures responsible for protein synthesis. While both prokaryotes and eukaryotes have ribosomes, their sizes and compositions differ.
Membrane Structure: The plasma membrane of prokaryotes contains a different type of lipid and lacks sterols (except in some archaea) compared to eukaryotes.
