Answer:
The principle of cross-cutting relationships states that a fault or intrusion is younger than the rocks that it cuts through

White blood cells make up approximately 1% of the total blood volume in a healthy adult, making them substantially less numerous than the red blood cells at 40% to 45%.
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
Answer: The correct answer is -
B) haploid.
Meiosis is a type of cell division that occurs during the process of formation of gametes particularly sexually reproducing organisms.
Gametes are reproductive, sex cells that are haploid (having half the number of chromosomes as their parent cell).
Thus, during meiosis a diploid parent cell gives 4 haploid daughter cells, called gametes (such as eggs and sperms).
Answer:
Answer is A. allow them to control all the variables involved.
Explanation:
Modelling in ecology means the use of constructed mathematical models for understanding of ecological processes and to predict or know how real it is for ecosystem to change.
Ecological modelling is useful in defining problems more precisely and clarity of concepts.
