6, how often does an egg cell leave an ovary, in an adult woman
7, how often does menstruation happen, in an adult woman
Answers
Answer:
°•°
Explanation:
1.fallopian tube
2.an unborn or unhatched offspring in the process of development, in particular a human offspring during the period from approximately the second to the eighth week after fertilization (after which it is usually termed a fetus)
3.First, the zygote becomes a solid ball of cells. Then it becomes a hollow ball of cells called a blastocyst. Inside the uterus, the blastocyst implants in the wall of the uterus, where it develops into an embryo attached to a placenta and surrounded by fluid-filled membranes.
4.Eggs live in ovaries, and the hormones that control your menstrual cycle cause a few eggs to mature every month. When your egg is mature, it means it's ready to be fertilized by a sperm cell. These hormones also make the lining of your uterus thick and spongy, which gets your body ready for pregnancy.
5.The fertilized egg attaches to the lining of the uterus. The placenta then develops. The placenta transfers nutrition and oxygen to the fetus from mother. If the egg does not become fertilized, the lining of the uterus (endometrium) is shed during menstruation.
6.The egg cell travels down the fallopian tube into the uterus. The moment the egg cell leaves the ovary is called ovulation. Once a girl has had her first monthly period, ovulation usually occurs once a month
7.The average menstrual cycle is 28 days long. Cycles can range anywhere from 21 to 35 days in adults and from 21 to 45 days in young teens. The rise and fall of levels of hormones during the month control the menstrual cycle.

Non vascular plants are quite commin in the forests along the coast of Norther California but are relatively rare in the ecosystems around Davis in the Central Valley. What aspects of the life cycle of these plants make it difficult for them to reproduce on our area
Answers
Answer:
The Central Valley of northern California is a region where there is little water supply, while nonvascular plants cannot efficiently store water and they have primitive traits that are dependent on water for reproduction.
Explanation:
The Central Valley of northern California is characterized to have little natural precipitation/snowmelt during the dry summer months. In addition, California's climate also has extended periods of drought. On the other hand, non-vascular plants such as mosses and liverworts, are a type of plant that lacks vascular tissues (xylem and phloem), and they also lack true roots, stems, or leaves. These plants cannot efficiently absorb and store water (which fundamental for survival), and thereby the success of these plants in establishing and reproducing in the ecosystems of the Central Valley is limited to their physiological tolerance to desiccation. Moreover, non-vascular plants may also exhibit primitive traits related to their reproductive cycle (e.g., a flagellated sperm) that are dependent on water for reproduction.
In mouse, genes X, Y and Z are on chromosome 2. The map of genes X, Y and Z is:
X--------20mu--------Y---------------30mu---------Z.
You cross an individual with genotype XXYYZZ to an individual with genotype xxyyzz, and F1 progeny are collected. Assume interference between regions (X-Y and Y-Z) is 40%. You then perform a cross between an F1 individual and an individual with genotype xYz/xyz. Among 1000 progeny, how many of them will be of the genotype xxyyzz?
Answers
Answer:
36 individuals xxyyzz
Explanation:
Available data:
X-Y = 20MUY-Z = 30MUCross: XXYYZZ x xyyzzF1= XxYyZzI = 40%2nd Cross: XxYyZz x xxYyzzF2 = 1000 individualsWe need to know how many individuals from the F2 are going to be xxyyzz
xxyyzz genotype is the result of a double recombinant event.
First, we need to analyze the given information:
→ Distances between genes
The genetic distance result from multiplying the recombination frequency of each region by 100 and expressing it in map units (MU). So, if we have the genetic distance we can divide it by 100 and get the recombination frequency:
Let us say that region I is the distance between X and Y. And region II is the distance between Y and Z.
GD = genetic distance
RF = Recombination frequency
GD (X-Y) = RF x 10020MU = RF x 100
20MU/100 = RF
0.2 = RF (Region I)
GD (Y-Z) = RF x 10030MU = RF x 100
30MU/100 = RF
0.3 = RF (Region II)
Now we have the recombination frequency of Region I and Region II.
→ Interference
Knowing the interference value will let us know the value of the coefficient of coincidence, which will also lead us to the number of individuals xxyyzz.
I = 40%
I = 1 - CC ⇒ CC = coefficient of coincidence
Clearing this equation gives us the value of CC
CC = 1 - I
CC = 1 - 40% = 1 - 0.4
CC = 0.6
To calculate the coefficient of coincidence, CC, we can also use the next formula:
CC = observed double recombinant frequency/expected double recombinant frequency
Now, we are interested in knowing the value of the observed double recombinant frequency.
Note:
observed double recombinant frequency = total number of observed double recombinant individuals/total number of individuals expected double recombinant frequency = recombination frequency in region I x recombination frequency in region II.So, to get the value of the observed double recombinant frequency, first, we need to get the value of the expected double recombinant frequency. And we can do it because we already have the recombination frequencies in both regions.
expected double recombinant frequency = recombination frequency in region I x recombination frequency in region II
- Recombination Frequency - RI = 0.2
- Recombination Frequency - RII = 0.3
expected double recombinant frequency = 0.2 x 0.3
expected double recombinant frequency = 0.06 = EDRF
Now that we know the value of the CC and the expected DRF, we can get the observed double recombinant frequency.
CC = observed double recombinant frequency/expected double recombinant frequency
- CC = 0.6
- EDRF = 0.06
CC x expected double recombinant frequency = observed double recombinant frequency
0.6 x 0.06 = observed double recombinant frequency
0.036 = observed double recombinant frequency = ODRF
Finally, as this is a frequency, we need to multiply it by the total number of individuals in the F2 to get the number of observed double recombinant individuals.
- ODRF = 0.036
- N = 1000
Double recombinant individuals = 0.036 x 1000 = 36 individuals xxyyzz.

Answers
Answer:
It provides ATP.
Explanation:
It is adaptive for the larger host cell to keep the engulfed cell alive, instead of digesting it as food because the engulfed cell provides energy in the form of adenosine triphosphate (ATP) to the host cell. The larger host cell is able to survive in anaerobic conditions with the help of engulfed cell alive so that's why we can conclude that the larger host cell keep the engulfed cell alive instead of killing it and used as a food source.
