Hello there!
The answer is enzymes.
Enzymes are biological catalysts, which means they decrease the amount of activation energy needed to start a reaction, therefore speeding up the rate of the reaction. They are part of the protein macromolecule group. Without them, our bodies would not process things efficiently or fast enough for us to live.
Hope I helped. Have a nice day.
Answer:
The longitude of the location of the ship is W
Explanation:
Here we have the time at the prime meridian as 2 pm while the time at the ship is 10 am. What this means is that the prime meridian is 4 hours ahead of the time of the location of the ship. Geographically, whenever a location is east of the prime meridian, it is ahead of the prime.
Answer:
C) Water will move out of the cell.
Explanation:
In microbial growth experiments, when a bacterium is placed in a Petri dish with a solution that contains dissolved salt (NaCl) - a hypertonic solution -, the result will lead to the <u>dehydration and shrinking of the bacterial cell</u>.
This condition will eventually cause the rupture of the cell, resulting in the diffuse of H20 molecules from the plasma membrane, that is, the water moving out of the cell.

Answer:
a. Her mother has zig-zag antennae.
b. Her brother has zig-zag antennae.
Explanation:
<u>Available data</u>:
- Antennae development ⇒ controlled by maternal effect
- Zig-zag coils are dominant
- Curly coils are recessive
- A female develops zig-zag coils
Maternal effect: Refers to the influence of the “environment provided by the mother” on the progeny phenotype. The mother´s genotype directly determines the progeny phenotype. Even though the progeny has a different genotype, it is irrelevant, as well as the father´s genotype or phenotype. This means that no matter what is the genotype of the offspring, all of them will express the same phenotype as their mother. The maternal effect is commonly seen in insects and might be seen in some mammals and plants.
So, if a female has zig-zag coils, this means that the mother also has zig-zag antennae and that all the brothers and sisters of this female ant have zig-zag antennae, independently of their genotype.
a. Her mother has zig-zag antennae ⇒ True. The trait is inherited from the mother.
b. Her brother has zig-zag antennae ⇒ True. The whole progeny will express sig-zag antennae.
c. This female carries the zig-zag allele ⇒ Not necessarily.
d. This female's offspring will have zig-zag antennae ⇒ Depends on it´s genotype
