Answer:
D: two jaguars per thousand hectares.
Explanation:
Population density refers to the computation of population by unit area. It is usually implemented in living organisms, generally in humans. It is a key geological term. In easy form, population density implies to the number of people existing in an area per square kilometer or hectare, etc.
So, two jaguars per thousand hectares is an example of population density as it involves the number of jaguars (population) per thousand hectares (per unit area).
A. They are consumed by the reactions they catalyze
Answer:
The endometrial lining is shed during menstruation and is then regenerated by the hormone estrogen.
Explanation:
The menstrual cycle can be described in terms of:
1. <u>OVARIAN cycle</u>: divided into
-Follicular phase of variable length lasting between 7 and 21 days.
-Ovulation
-Luteal phase which is fairly constant and lasts between 12 and 16 days.
The most common cycle length is 28 days and this occurs in 15% of women in their reproductive age
.
The duration of flow is between 2-6 days.
2. <u>ENDOMETRIAL cycle</u>: divided into
-Proliferative phase where there is increase in growth of the functional layer and the endometrial glands under the influence of oestrogen.
-Secretory phase where endometrial changes are influenced by progesterone activity.
The endometrium is made up of the basal layer and the functional layer.
The basal layer remains intact throughout the cycle while the functional layer is shed during each menstruation.
Answer:
The answer is E.
Explanation:
The question is incomplete. Here is the complete question:
An XXY chromosome constitution produces ________ development in humans and _________ development in fruit flies.
a. female; female
b. male; male
c. female; male
d. male; female
e. male, intersex
Normally, possessing two sex chromosomes for humans, having 3 sex chromosomes is an abnormality but it still results in a development of a male, who is infertile.
Fruit Flies are a species which possess 3 sex chromosomes normally, and in the cases in which there are 2 X choromosomes, it encourages the development of intersex fruit flies. Situations where there are 3 X choromosomes present result in female fruit flies and where there is only a single X chromosome result in male fruit flies.
I hope this answer helps.
