Flowers are a collection of _____ tissue produced by some plants.
Lostsunrise [7]
There are choices for this question namely:

1. Sterile
2. Reproductive
3. Both
4. Neither

The correct answer is that flowers are a collection of reproductive tissue produced by flowering plants (angiosperms). The flower is a reproductive organ of the plant. It is composed of the male organ (stamen) which produces the pollen and the female organ (ovary) which receives the pollen. Once the ovary receives the pollen either from the same plant or from another through pollination, the ovule (part of the ovary) will then become the seed and the ovary will become the fruit. The seed is the "embryo" of the plant wherein if planted, it will grow to a new plant.

Which portions of the large intestine are located in the pelvic cavity?
Whitepunk [10]

The sigmoid colon, which begins in front of the pelvic brim, is a section of the large intestine that is located in the pelvic cavity.

The sigmoid colon typically measures 25 to 40 cm in length (10 to 15.75 in). As a continuation of the descending colon, the sigmoid colon is a "S"-shaped section of the large intestine that starts in front of the pelvic brim and changes into the rectum at the level of the third sacral vertebrae.

<h3>The large intestine is it located in the pelvic cavity?</h3>

The urine bladder, the remainder of the large intestine (the bottom region), and the internal reproductive organs are all located in the pelvic cavity, which is the lower part.

<h3>Which digestive system organ is located in the pelvis?</h3>

The inferior portions of various abdominal viscera are located in the larger pelvis (terminal ileum, cecum, sigmoid colon).

<h3>Where in the abdominal cavity is the big intestine?</h3>

From the ileocecal junction to the anus, the large intestine continues the ileum for 1 to 1.5 meters. The majority of the large intestine is found in the abdominal cavity, and the remaining part is found in the pelvic cavity.

What determines at what angle a beam of light takes when it reflects off a mirror.
FromTheMoon [43]
Reflected light obeys the law of reflection, that the angle of reflection equals the angle of incidence. For objects such as mirrors, with surfaces so smooth that any hills or valleys on the surface are smaller than the wavelength of light, the law of reflection applies on a large scale.

You perform an experiment in which chromatin is isolated from sea urchin sperm cells and briefly digested with micrococcal nucle
irga5000 [103]

Answer:

a) DNA fragments associated with histone proteins are all multiple in length (i.e., 260 bp, 520 bp, 780 bp, etc), thereby suggesting the presence of a pattern of organization in the chromatin  

b) it suggests that each unit of organization (ie, each nucleosome) consists of 260 bp associated with chromatin proteins

Explanation:

The nucleosome is considered as the basic unit of chromatin. A nucleosome consists of approximately two turns of DNA wrapped around a core of eight histone proteins (i.e., a histone octamer). The histone octamer consists of two copies of each of the histones H2A, H2B, H3, and H4. Moreover, the nucleosomes are connected together by linker DNA sequences which vary between 10 and 100 bp in length.
