n the 1600's, Robert Hooke, and English scientist, used a crude microscope to examine bits of cork. Cork is derived from the bark layer of certain trees. Upon seeing the cork under the microscope, Hooke named the spaces within the cork 'cells', because they looked like empty rooms of a monastery. Although he coined the term cell, an ironic feature of cork is that it is dead plant material. Knowing this, what feature of cells would Robert Hooke NOT have been able to observe under the microscope while looking at cork?
Answer:
the answer is C: he would not be able observe cork cells dividing to form new cells

Imagine animal cells had chloroplasts. Chloroplasts allow plant cells to perform photosynthesis. How do
you think this would change the way animals gain energy?
Answer:
It would change the way they gain energy by the animals not having enough things in the body to get it functioning right.
Explanation:
think of it as gas our cars need gas to run, so do animals and us but our gas is food
If animal cells had chloroplasts, it means animals would be able to gain energy directly from sunlight by being able to manufacture carbohydrates as a food source.
The presence of chloroplast would allow an animal cell to photosynthesize and manufacture foods in the form of carbohydrates.
[tex]6CO_2 + 6H_2O ---> C_6H_1_2O_6 + 6O_2[/tex]
The food can be broken down during respiration in order for the energy to be extracted.
[tex]C_6H_1_2O_6 + 6O_2 ---> 6CO_2 + 6H_2O[/tex]
This would be in addition to animals' ability to gain energy from external food sources through the same respiration.

, What behavioral genetic research finding seems to support the conclusion that the effect of growing up in the same home environment is rather minimal? a. The personality traits of adoptive siblings raised in the same family are correlated around .05. b. The personality traits of monozygotic (MZ) twins are correlated at .50 on average. c. The personality traits of dizygotic (DZ) twins are correlated at .30 on average. d. The personality traits of adoptive siblings raised in the same family are correlated above .25.
Answer:
a. The personality traits of adoptive siblings raised in the same family are correlated around .05.
Explanation:
Both genes (inheritance) and environment play roles in literally everyone human traits including human personality. Nonetheless, recent research involving adoptive siblings and monozygotic twins, which are genetically identical, strongly suggest that there is a predominant genetic influence on this human trait. In consequence, environmental factors play minor roles in human behavior. In the case above indicated (i.e., adoptive siblings in the same home), the low correlation value shows a minor effect of the environment on the personality.

1. What is the weight of an object that has a base of 3 square meters and has a pressure of 21 newtons per square meters?
Answer:
63N
Explanation:
To calculate the weight (force) that an object exerts, the formula is used:
Pressure = Force / Area
Where; P = pressure
F = applied force
A = the surface area the
force is applied to
According to the question; P= 21N/m^2,
F= ?, a = 3m^2
Force = pressure × area
Force = 21 × 3
Force = 63N
Hence, the weight of the object is 63N

All living cells must maintain homeostasis or internal stable conditions in order to survive. Which of the following processes would best help a cell to maintain these conditions
(SC.6.1.142)
АО
using energy
BO
creating DNA
using carbon dioxide
creating water molecules
Answer:
None of the options provided is correct but some are close
Explanation:
One of the ways in which a cell maintain homeostasis is by regulating what goes in and out of the cell through the cell membrane (which is a semi-permeable barrier). The amount of water is highly regulated by the cell in this case so as to regulate osmosis (movement of water molecules from a region of higher concentration to a region of lower concentration). Other substances regulated are oxygen and carbon dioxide.
NOTE: The cell does not create water molecules neither does it use carbon dioxide to maintain homeostasis, it rather regulates these two compounds.

Answer:
positive, negative, or no effect
Explanation:
It was right on the test
Positive, Negative or no effect can a chromosomal change can have on an organism. So, the correct option is (A).
What is Chromosomal change?When there is an increase or loss of chromosome number from the normal number of chromosomes which is 46, it is called aneuploidy. A common form of aneuploidy is trisomy which is the presence of an extra chromosome in cells.
"Tri-" is Greek for "three" which define as the people with trisomy have three copies of a particular chromosome in their cells instead of the normal two copies.
Chromosomal abnormalities can occur when an accident occurs when the egg or sperm are being formed or during the early developmental stages of the embryo. Maternal age and certain environmental factors may play a role in the occurrence of genetic errors. There are Positive, negative, or no effect in the chromosomal change.
Thus, Positive, Negative or no effect can a chromosomal change can have on an organism. So, the correct option is (A).
