Answer:
Unlike heirloom seeds, if one saves a hybrid seeds, one will not get same plant again.
Explanation:
Hybrid seeds they are cross pollinated. It is the main contributor in agriculture.
They does not reproduce so they do not save seeds from hybrids.
Heirlooms are open pollinated. Thy can be harvested and replanted and it can be grown year after year.

which characteristic could help you distinguish between bacteria and fungi?
Answer:
Bacteria are single-celled organisms but most fungi are not.
Explanation:
Bacteria are single-celled microscopic organisms that are characterized by the presence of incipient nucleus and few membrane-less cell organelles. Fungi, singular fungus, are eukaryotes that are characterized by the presence of chitin in the cell wall. All bacteria are prokaryotes. All fungi are eukaryotes
Answer:
A) Bacteria are single-celled organisms, but most fungi are not.
Explanation:
Bacteria are microscopic single-celled organisms with immature nuclei have an immature nucleus and a few membrane-less cell organelles. Fungi (plural fungus) are eukaryotes distinguished by the presence of chitin in the cell wall. Prokaryotes are all bacteria. Fungi are all eukaryotes.

Describe how water is important to plants in terms of:
i) making food in plants
ii) the plant's shape
iii) hydrolysis and dehydration
Answer:
i) In terms of food production in plants, water is essential to plants as it is the evaporation of water that occurs in leaves that allows carbon dioxide to enter and to begin photosynthesis.
(ii) In terms of the shape of the plant, water is important to plants as the hydration of the cells of a plant allows the cell walls to retain their shape and thus give structure to the plant.
(iii) In terms of hydrolysis and dehydration, water is essential for plants because water is not a photosynthesis reactant or respiratory product.
Explanation:
i) Water is important in terms of making food in plants:
Water is required for the germination of seeds and as soon as growth starts water serves as a carrier in the distribution of mineral nutrients and plant food.
ii) Water is important in terms of the plant's shape:
Responsible for turgor pressure in cells (Like air in an inflated balloon, water is responsible for the fullness and firmness of plant tissue. Turgor is needed to maintain cell shape and ensure cell growth.)
iii) Water is important in terms of hydrolysis and dehydration:
During the process of photosynthesis, six molecules of carbon dioxide and six molecules of water react in the presence of sunlight to form one glucose molecule and six molecules of oxygen.
The role of water is to release oxygen (O) from the water molecule into the atmosphere in the form of oxygen gas.

Which statement describes the electron sharing between two oxygen atoms?
Each oxygen shares one electron with the other.
Each oxygen shares two electrons with the other.
Each oxygen shares eight electrons with the other.
Each oxygen shares six electrons with the other.
When two oxygen atoms get close to each other, the attractions from the nucleus of both atoms attract the outer electrons.
What is Electrons?A negatively charged subatomic particle known as an electron can either be free or attached to an atom (not bound). The nucleus of an atom is made up of electrons, protons, and neutrons together.
The positive charge of a proton balances the negative charge of an electron. An atom is in a neutral condition when it has the same number of protons and electrons.
There are several ways in which electrons differ from the other particles. They are substantially less massive, exist outside of the nucleus, and show both wave- and particle-like properties.
Therefore, When two oxygen atoms get close to each other, the attractions from the nucleus of both atoms attract the outer electrons.

What are the similarities between prokaryotes, eukaryotes and viruses?
An organism was found. It is unicellular, but its one cell does contain a nucleus and the cell is autotrophic. What type of organism is this?
A
animalia
B
protista
C
bacteria
D
fungi
Answer:
B protista
Explanation:
The cell is unicellular, so it can not be an animal, which are all multicellular.
It contains a nucleus, which means it cannot be prokaryotic (it cannot be bacteria)
The cell is autotrophic, which means it cannot be a fungus, which are heterotrophs
Therefore, the organism must be a protist, so the answer is B, protista.

Using the law of conservation of mass, what is the mass, in grams, of the product in the given reaction?
Reactant 1 (35 grams)+ Reactant 2 (115 grams) →Product (? grams)
A. 80
B. 140
C. 150
D. 75
Answer:
The correct option is;
C. 150
Explanation:
By the law of conservation of mass we have that in a closed system, the mass of the items in the system can not be destroyed or created by a physical process or chemical reaction
In the given chemical reaction process we have;
Reactant 1 (35 grams) + Reactant 2 (115 grams) → Product = ((35 + 115) grams)
∴ Reactant 1 (35 grams) + Reactant 2 (115 grams) → Product (150 grams)
The mass of the product = 150 grams.

wildlife monitoring technology is an important of protecting our ecosystems and the populations that live within them. How do you think advancements in the kind of technology could help protect burrowing owl populations.
Answer:
Plant more trees in areas that don’t have enough to make up for the loss of habitat. Also integrating large bird homes and sanctuaries around the power plants could help the owls settle back down in a semi-familiar environment.
Explanation:
Reduce threats to wildlife in the best remaining wilderness areas on Earth to keep their numbers stable or growing, to ensure sustainable fishing and hunting, and to settle disputes between people and wildlife.
What is the importance of wildlife monitoring technology?We can ensure that widespread species remain widespread and that unusual, threatened, and endangered species continue to get protection and aid thanks to data gathered through wildlife monitoring.
We may monitor pack dynamics, movements, ecological effects like feeding, mating, and nesting behaviors, illness outbreaks, snare incidents, and other human conflict issues through daily monitoring.
Therefore, We have a greater grasp of the occurrence, distribution, and status of animals in the preserves because of monitoring initiatives.

Why does evolutionary theory absolutely require the earth to be very
old?
Answer:
Because it takes time for the animals to adapt to their environment, and change their DNA
Answer:
Because evolutions don't happen overnight, it takes years and years for an organism to develop an evolution. So, the earth has to be old, because if we look at the earth when it was young, then we don't really see any evolutions. However, if we look at it when it's old, we can see that there were many evolutions. I hope this helps!

3. Why were germinating seeds used instead of dormant (non-
germinating) seeds?
Answer:
An important function of seed dormancy is delayed germination, which allows dispersal and prevents simultaneous germination of all seeds. ... Many species of plants have seeds that delay germination for many months or years, and some seeds can remain in the soil seed bank for more than 50 years before germination.
how are proteins made in animals and humans
Answer:
Through protein synthesis of course...
Explanation:
DNA and RNA do many steps such as translation, transcription, and more to form protein codons and code them into amino acids. Then, thousands of amino acids are oined together to make proteins, which regulate body function and catalyze chemical reactions (enzymes). Ribosomes are also involved in this action. To make proteins, nitrogen is needed for the plant to use, and that comes mainly from nitrate ions in the soil, and gets into the plant by active transport.
