Answer:
1. Alternation of generations
2. Differentiation
3. Germination
4. Mersitematic cells or Meristem (tissue)
5. Perennial
6. shoots
7. Vascular Cambium
Explanation:
Alternation of generations is a process in the life cycle of a plant and even algae. The alternation part occurs between the sporophyte and gametophyte. A sporophyte is formed when two haploid gametes come together forming a diploid zygote. When the sporophyte matures, it will eventually gain a reproductive organ that would release spores that are haploid spores. These spores become gametophytes. When these gametophytes start to pair up, they become sporophytes. So the cycle begins again.
The meristem is a tissue that is made up of cells called merstematic cells. They produce undifferentiated cells which can specialize into other cells to serve different purposes. Meristems are usually found in areas of the plants that grow.
Perennial means "through the years," and so they are plants that are expected to live a long life, often more than two years. These plants can grow out again from the same roots after they die, so you do not need to replant them.
The growth that starts from the seed that goes in the upwards direction is called shoots, while the growth that goes downwards are called roots. Shoots are the starting point of the growth of the different parts of the plant that are above the ground, like the stem, leaves and the like.
Differentiation is a process where cells start to acquire specific traits to do specific and different functions. Some of the cells that differentiate will not be able to reproduce new ones, some of them die, and the others skip the mitosis stage.
Germination occurs mostly in plants. It is the growth of an organism that starts from a dormant state or a seed.
As plants grow taller, they also grow wider. The vascular Cambium produces undifferentiated cells that form the bark and the woody cells which increases the girth or the wideness of the plant.

where did earths water come from
Answer:
Two rocky material collision cause water formation
Explanation:
Earth is rich in water, and has been for a few billion years, but scientists are still debating just where all that life-sustaining liquid came from. At least some of it was thought to have been brought here by comets or asteroids, but that idea still falls short in explaining how so much water ended up on Earth’s surface – and deep below, as well. Now, a team of scientists at Arizona State University (ASU), led by Peter Buseck, has come up with a new proposal. The new peer-reviewed paper was published in the Journal of Geophysical Research: Planets on October 9, 2018.
The new research suggests that Earth’s water came from both rocky material, such as asteroids, and from the vast cloud of dust and gas remaining after the sun’s formation, called the solar nebula.

Earth’s ocean water is similar to that found in asteroids. That’s one reason scientists have long thought that most earthly water came from an asteroid bombardment in the days of the early solar system. The ratio of deuterium – a heavier hydrogen isotope – to normal hydrogen is a unique chemical signature in various water sources. In the case of Earth’s oceans, the deuterium-to-hydrogen ratio is close to what is found in asteroids. But, according to Steven Desch, also at ASU and one of the team members:

B. Converting rural pastureland into a new shopping center
O
C. Converting an old shopping mall into a community college
O
D. Drawing an urban growth boundary around an area
Answer:
Putting a parking garage on an unused lot inside a city- A.
ANSWER:
The correct option is A: Putting a "parking garage" on an unused lot inside a city.
EXPLANATION:
Infill takes place when a land or area not being used is put to use for public good. This does not mean that an area which is old is converted to a new area or is brought to use. The infill of an unused area by putting a parking garage simply brings the area under use. However, if the area or land was under cultivation or had an old building on it and was converted to a parking lot, it would not have been infill.why are mustard seeds and groundnut called oil seeds

Explanation:
Someone with A antigens will not have
antibodies.
The statement Someone with A antigens will not have antibodies is incorrect. In the ABO blood group system, individuals with type A blood have A antigens on the surface of their red blood cells, and they can have antibodies in their plasma. Specifically, they will have anti-B antibodies, which are capable of attacking and destroying red blood cells that carry B antigens. This is because the immune system of a person with type A blood is naturally sensitized to recognize the B antigen as foreign.
To clarify, here is the typical antibody and antigen profile for the ABO blood group system:
- Type A blood: A antigens on red blood cells, anti-B antibodies in plasma.
- Type B blood: B antigens on red blood cells, anti-A antibodies in plasma.
- Type AB blood: A and B antigens on red blood cells, no anti-A or anti-B antibodies in plasma.
- Type O blood: No A or B antigens on red blood cells, both anti-A and anti-B antibodies in plasma.
Therefore, a person with type A blood will have A antigens but will also have anti-B antibodies, not anti-A antibodies. This is crucial for blood transfusions, as a person with type A blood can receive type A or type O blood, but not type B or type AB blood, because the anti-B antibodies in their plasma would react against the B antigens on the donor red blood cells.
which Statement correctly describes why cells are so small? a) when cells are small the movement of food and waste can be efficiently handled by the cell membrane b) when cells are small they can adapt their shape more easily to fulfill their specific function c) when cells are small their internal parts can better support the cell membrane d) when cells are small they can easily work together to form tissue
Answer:
a) when cells are small the movement of food and waste can be efficiently handled by the cell membrane
Explanation:
Cells need to get their nutrients and waste in and out of their cell membrane every quickly. Cells are hard workers anyway! The other options also don't make much sense. The cell shape doesn't mean much to their function, and size doesn't impact shape. The cell's internal parts (mitochondria, vacuole, etc) don't support the cell membrane, they have their own functions to focus on. Cells don't work together in tissue but they can interact with each other when needed.
Answer:
The statement (a) correctly describes that why cells are so small.
Explanation:
Cells are formed of cytoplasm enveloped by a phospholipid bilayer. In the cells of plants, a supplementary cell wall also prevails. The cytoplasm accommodates various metabolic activities that need a spontaneous supply of nutrients. During the same time, metabolic wastes originate from these reactions, which are required to be eradicated. All this uptake and discard of nutrients and waste components occurs by mediation across the cell membrane via passive, active, or facilitated transport.
In the absence of any circulatory system, these cells depend entirely on the process of diffusion through the membrane. The brisk interchange of molecules can only take place if diffusion occurs over brief distances. Thus, this rate of uptake of nutrients within the cells and discarding of wastes into the external surroundings hugely relies upon the cell surface, which is restricted by the cell membrane. Thus, surface area of the cell is one of the limiting factors to monitor the rates of diffusion of these molecules. Therefore, when the cells are small, their wastes and food can be handled effectively by the cell membrane.

Which of the following crime scene search patterns has investigators start from a center area and move outward? A. strip method B. grid method C. zone method D. wheel method
Answer:
D. wheel method
Explanation:
Just like any other job, planning out is a vital step involved in criminal investigation cases. Solving a crime case requires alot of attention to details to preserve the evidences and to take best step onwards. Several methods are used by law enforcement agencies which use six crime scene search patterns including Line method, Grid method, Zone method , Spiral method, Wheel method and Strip method respectively.
In wheel method,many crime scene searchers and personnel are involved.In this method, every searcher or employ Starts from the middle of an imaginary circle and moves out from the direction of the center to outwards just like spokes of a bicycle wheel. Although it is a reliable method of crime scene investigation but still evidences can be destroyed from the center of the area therefore extreme caution should be taken while searchers are entering in the hub of the area.

A boat traveled from a bay into a freshwater lake and brought a nonnative plant to the lake. If the new plant adapts to the freshwater environment, which is the most likely consequence in the lake?
- Water temperature will fluctuate rapidly.
- The water will become brackish.
- Some native plant populations will increase.
- Some native plant population will decline.
Answer:
- Some native plant population will decline
Explanation:
If the boat brings in a nonnative plant into the lake, than that means that lake will get an invasive species. The plant that will be brought will be an invasive species as it is not native to that lake. The invasive species usually manage to out-compete the native species, often resulting in rapid increase in the numbers of the invasive species, and rapid decline, or even extinction of some of the native species as they are not able to compete with the invasive species.
Answer:
Some native plant population will decline.
