loop of Henle concentration gradient
Answers
Answer:
The Loop of Henle serves to create a concentration gradient throughout the nephron which helps increase the reabsorption of water and certain ions. In the thin descending limb, water is very permeable and is reabsorbed due to the existing concentration gradient in the medulla.
in monohybrid cross between a pure breed plant that produces blue flowers (BB)and a pure breed plant that produces white flowers.The f1 generation produces only blue flowers. By means of a labelled cross diagram,state the type of flower you will expect if the f1 generation is self pollinated
Answers
Answer: If the F1 generation is self-pollinated, 75% of the flowers will be blue, while 25% will be white.
Explanation:
Monohybrid cross between blue and white: BB x bbThe cross produces 100% Bb --> blue is dominant, so all the flowers will be blue. This is the F1 generation.If F1 is self-pollinated, it will be Bb x Bb.The cross will produce 25% BB, 50% Bb, and 25% bb.Since blue is dominant, 75% of the flowers will be blue, while 25% will be white.Pictures:

This tutorial will take you step by step through the question.
In cucumbers, dull fruit (D) is dominant to glossy fruit (d), and orange fruit (R) is dominant to cream-colored fruit (r). The gene that codes for dull versus glossy assorts independently from the gene that codes for orange versus cream-colored. A plant that has dull and orange fruits is crossed to a plant that has dull and cream-colored fruits. The cross produces eight total progeny, with three plants that have dull and orange fruits, three plants with dull and cream-colored fruits, one plant with glossy and orange fruits, and one plant with glossy and cream-colored fruits.
Determine progeny phenotypic ratios - texture. To determine the actual genotype of the parents from among the possible genotypes identified in the previous step, separate the cross into two single-locus crosses, looking at the inheritance of each trait by itself. Start with the texture characteristic.

B. The cells store more nutrients
C. The cells degrade more protein
D. The cells divide more frequently
Answers
Answer:
A
Explanation:
different types of cells use different amounts of energy
Some cells, such as human nerve and muscle cells contain many more mitochondria than do cells such as skin cells, some cells have more mitochondria than others as they use more energy. Thus option A is correct.
What are the characteristic feature of mitochondria ?
Mitochondria is commonly called as the “Powerhouse of the cell, these are double membrane-bound organelle present in most eukaryotic organisms located in cytoplasm and function as cell's “digestive system.”
They involve in break down of nutrients and generate energy-rich molecules, cellular respiration occur within the mitochondria, was first described by a German pathologist named Richard Altmann in the year 1890.
The mitochondrion is rod-shaped structure found in both plant and animal cell, size ranges from 0.5 to 1.0 micrometre in diameter, consist outer membrane, an inner membrane, and a gel-like matrix.
The outer and inner membrane are composed of proteins and phospholipid layers which is separated by the intermembrane space.

Which list correctly orders the parts of an atom from heaviest to lightest in mass?
А
electron, proton, nucleus, neutron
В.
neutron, proton, nucleus, electron
С.
proton, neutron, electron, nucleus
D
nucleus, neutron, proton, electron
Answers
Answer:
nucleus, neutron, proton, electron
Explanation:
The list that correctly orders the parts of an atom from heaviest to lightest
in mass is as follows:
nucleus, neutron, proton, electron
The nucleus of an atom is composed of a tightly packed proton and
neutrons.
This makes the nucleus very dense and small. The nucleus are surrounded
by a negatively charged electron.
The nucleus contribute to most of the weight of an atom.
This makes the nucleus the heaviest.
The neutron is found in the nucleus of an atom. The neutrons are
electronically neutral. The neutron are slightly heavier than proton.
Therefore, the neutron is the second heaviest part of an atom.
The proton is found in the nucleus of an atom. They a positively charged.
The proton is the third heaviest.
The electron revolves around the nucleus and are very light. In fact the
nucleus contributes to 99.9 % of the weight of an atom. This shows how
light the electrons are.
Therefore, the order from the heaviest to the lightest is as follows:
nucleus, neutron, proton, electron
