Answer:
Explanation:
Cell transport refers to the movement of substances across the cell membrane. Probably the most important feature of a cell's phospholipid membranes is that they are selectively permeable. A membrane that is selectively permeable, or semipermeable, has control over what molecules or ions can enter or leave the cell, as shown in Figure below. This feature allows a cell to control the transport of materials, as dictated by the cell's function. The permeability of a membrane is dependent on the organization and characteristics of the membrane lipids and proteins. In this way, cell membranes help maintain a state of homeostasis within cells (and tissues, organs, and organ systems) so that an organism can stay alive and healthy.

WOULD THERE BE ANY BACTERIA
IN AN AQUARIUM?
A balanced
aquarium
contains certain animals as
well as some plants. How
many kinds of animals can
you make out in the
aquarium shown here ? Name
any two such animals.
.............
...............
Do you think there would be
some bacteria in it? If so, in
which part of the aquarium
would they be occurring in
abundance and what for?
.................
Answer: yes, many different kinds
Explanation: bacteria are everywhere and so will be found in aquaria. Aquarium health is dependent on bacteria. Fish excrete ammonia which is toxic. Bacteria such as Nitrosomonas and Nitrococcus convert ammonia to nitrite, and Nitrobacter converts nitrite to nitrate which is relatively harmless. Bacteria such as Pseudomonas stutzeri and Bacillus subtilis remove nitrate and organic waste. There are also bacteria in fish intestines, and other bacteria that can cause fish diseases or create undesirable conditions such as Pseudomonas fluorescens, Vibrio, Flexibacter or Aeromonas and anaerobes that reduce sulphates to hydrogen sulphide.
Chemical reactions can occur in the cells of living things.

The style is the female reproductive part of the plant. Do some research online to learn more about the
style. Based on your observations and your research, how does the style play a role in reproduction?
✓
The Style part of a flower is the female part of a flower (like the question says), the way the Style plays a role in reproduction is how it supports the stigma and connects it to the ovary. This is a major role in reproduction for the flower, because it's the location where pollen tubes travel to deliver sperm cells to the egg.
Answer:
The style is the female reproductive part of the plant. Do some research online to learn more about the style. Based on your observations and your research, how does the style play a role in reproduction?
Explanation:
Inbreeding can cause physical defects because _____________ are passed on to the next generation.
a.
DDT
c.
PCBs
b.
estrogen
d.
deleterious recessive genes
Answer:
d. deleterious recessive genes
Explanation:
Inbreeding occurs when offsprings result from two individuals who have a similar genetic sequence because they are closely related. The offsprings borne are prone to be defective because of the similarity between their parents' genes. Inbreeding depression also occurs because the offsprings are not physically fit and can easily succumb to death.
The opposite of inbreeding is crossbreeding which prevents the negative traits that are associated with inbreeding.

Why does blue light cause a negative photosynthesis rate? (If algae is grown under blue light, why is the rate of photosynthesis slower than other colors?)
Blue photons drive the photosynthetic reaction, although from an energy standpoint, one might consider them less efficient than green or red photons because their high energy isn't fully utilized; some of the energy is essentially lost compared to photosynthetic photons with a longer (less energetic) wavelength.

Where does the oxygen released during photosynthesis come from
Answer:
Oxygen liberated during photosynthesis comes from the splitting or hydrolysis of water in the green plants. Cornelius van Niel experimentally proved for the first time that the oxygen liberated during photosynthesis comes from water and not from carbon dioxide.
Answer:
Oxygen liberated during photosynthesis comes from the splitting or hydrolysis of water in the green plants.
Oxygen is just a by product of this splitting, and will be removed from the plant.
it was proven by Cornelius Van Niel that oxygen liberated during photosynthesis comes from water not carbon dioxide

TYPES OF LEVERS
Name
Classify the following levers as first, second or third class.
Answer:
First class lever
Second class lever
Third class lever
First class lever
First class lever
Third class lever
Second class lever
Second class lever
Explanation:
A lever is one of the types of simple machine. It is used to rotate on a fixed point. Load, effort and fulcrum are the three important parts involved in the functioning of lever. In the first class lever, the fulcrum is situated in the middle of the load and the effort. In the second class lever, the load is situated in the middle of the fulcrum and effort. In the third class lo=ever, the effort is situated in the middle of the fulcrum and the load.
