how does concentration of tomato juice affect germination of seeds
Answer: The greater the concentration of inhibitors the less chance the substrate molecules have of binding with the active site (hence reactions slow and no germination). ... My results do show that tomato juice has a significant effect on the germination of cress seeds.

List ten adaptions that pinus plants display that allows them to survive a terrestrial model of life
Answer:
1) Growth Pattern
2) Conical Shape
3) Needle-shaped leaves
4) Pine needles
5) Waxy coating
6) Chemicals
7) Dark-colored needles
8) Thick bark
9) Ever growing roots
10) Small surface area of pine needles
Explanation:
Pinus plants are coniferous plants that are evergreen and long lived. They are usually found in the Northern Hemisphere and few parts of the Southern Hemisphere. Their adaptations include;
1) Growth Pattern: Pinus plants grow very closely to each other, creating a dense setting that helps to preserve warmth.
2) Conical Shape: Their conical shape helps them shed off snow and helps them produce enough food through photosynthesis by staying green all year.
3) Needle-shaped leaves: This helps reduce moisture loss.
4) Pine needles: This reduces moisture loss through transpiration.
5) Waxy coating: The waxy coating of their pine needles protect them from harsh weather like drying winds. It also protects them from sap that cause may freeze.
6) Chemicals: The chemicals present prevent wildlife from eating them.
7) Dark-colored needles: This helps them absorb heat from the sun
8) Thick bark: Protects against cold
9) Ever growing roots: Their roots do not stop growing even in winter so there is always moist and nutrients.
10) Small surface area of pine needles: Their small surface area helps in moisture retention.

A culture of living cells includes a solution called a _____.
A) concentration
B) slide
C) flask
D)medium
Answer:
D)Medium
Explanation:
A culture of living cells is grown over a solution that is called as a growth medium. A growth or culture medium can be in the form of solid, semi-solid or liquid. It is typically designed to facilitate the growth of the living cells of plants, animals, humans and microbes.
Which kingdom would a species be classified in if it has a nucleus, cell walls and
chloroplasts, gets energy through photosynthesis, and is an autotroph?
A.Protista
B.Fungi
C.Plants
D.Animals
Answer:
C. Plants
Explanation:
Taxonomy can be defined as the process of naming, classification and description of living organisms such as plants and animals, based on similarities or characteristics e.g eyes, number of legs, etc.,
The eight (8) biological classification (taxonomy) used for grouping and organizing organisms are; Kingdom, Domain, Phylum, Family, Order, Class, Species and Genus.
Additionally, the three (3) domain in which living organisms can be classified are: Bacteria, Eukaryote, and Archaea.
Thus, taxonomy helps scientist to have a good understanding and knowledge when studying various organisms.
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
In Biology, producers are the living organisms that are capable of manufacturing their own food and as such can provide energy or food for the other living organisms (consumers) in a food chain.
A producer gets energy from the sun and converts it into food. The cells found in producers are capable of converting the energy received directly from the sun into food through a process generally referred to as photosynthesis, converting carbon dioxide from the air, water from the soil, minerals and energy from the sun into organic nutrients.
In the ecosystem, producers are autotrophs or self-feeders such as plants.
Hence, the kingdom in which a species would be classified in if it has a nucleus, cell walls and chloroplasts, gets energy through photosynthesis, and is an autotroph is the plant kingdom (Plantae).
Answer:
C. Plants
Explanation:
Plants are multicellular and most don't move, although gametes of some plants move using cilia or flagella. Organelles including nucleus, chloroplasts are present, and cell walls are present. Nutrients are acquired by photosynthesis (they all require sunlight).
Which type of solution is best for use in IV bags at the hospital when patients can't afford to have their cells grow or shrink?

Explanation:
how is DNA changed to make a Genetically Modified organism.
Answer:
GM is a technology that involves inserting DNA into the genome of an organism. To produce a GM plant, new DNA is transferred into plant cells. Usually, the cells are then grown in tissue culture where they develop into plants. The seeds produced by these plants will inherit the new DNA.

Explanation:
Answer:
By around 6 million years ago, waters rushing off the Rockies had formed the mighty Colorado River. As the plateau rose, the river cut into it, carving the canyon over time. Smaller rivers eventually cut the side canyons, mesas and buttes that are so characteristic of the canyon today.

HELP!!!! two questions pls :)
Answer:
1.
To back up the scientist, when a person is more fit, their breathing will return to a normal rate faster than average, as B's rate returned faster than everyone else's, they are more fit.
Another reason the scientist could be right, is when a person is very athletic and fit, their resting heart beat is lower than an average person's heart rate. As person B has the lowest at 10, this would make them more fit.
2.
If the scientist counted wrong at all while measuring breath rates, the results could be wrong.
If each person did a different form of exercise, the results could also be wrong as different forms of exercise for each person would make the expirement inconclusive. (some exercises take more from the body than others).
