Introduced species can harm our planet because in some regions of the world we are not prepared for their type of species, which can all in all cause damage.

Carbon dioxide, nitrous oxide, and methane
Explanation:
Answer:
47 chromosomes
Explanation:
Meiosis is a kind of division that reduces the chromosome number of the daughter cells by half i.e. 2n - n. It occurs only in reproductive cells to produce sex cells or gametes. In humans, meiosis occurs to produce gametes (egg and sperm) that have 23 haploid chromosomes.
N.B: Somatic human cells have 46 chromosomes
According to this question, a meiotic error occurred during gamete formation, resulting in an egg that has 24 chromosomes. If that egg is fertilized by a normal sperm i.e. sperm with 23 chromosomes. A zygote that posseses (23 + 24) = 47 chromosomes will be produced.
Answer:
d) Organisms are open systems as they can create energy from their environments. The first law of thermodynamics states that energy can not be created or destroyed, it can be only changed or transferred from one form to another, like radiant energy to heat, motion energy to electrical, chemical to mechaqnical energy, among other examples. This law is also called: the law of conservation of energy.
Explanation:
Answer:
To determine the osmolarity of two types of apples in this experiment they use four sucrose solutions and twenty-four apple cylinders. They let these cylinders stand overnight in separate beakers of sucrose solutions, and repeat the procedure for the second variety. For the first variety, they record the temperature for the sucrose solution and remove the core to determine their combined mass. Then they will record the final masses and calculate percent change by using the percentage change in mass formula. After, they repeat these same steps for the second variety.
