Answer:

The sex chromosomes (X and Y) determine whether a cat will be male or female. Each cat has a pair of sex chromosomes with the possible combinations of XX (female) and XY (male). The X chromosome also carries the coding gene for the black and orange colors in a calico's coat.

Explanation:

Female calico cats have two X chromosomes and therefore have two chromosomes with color code. Only if the cat gets one orange-coded X and one black-coded X, will she be calico, expressing both black and orange coloration.

Because male cats have one X chromosome with code for black or orange and one Y chromosome with no color genes, they cannot technically be calico. They'll only express either black or orange, but not both.

henke vg, bateman bt, leffert lr. focused review: spinal anesthesia in severe pre-eclampsia. anesth analg. 2013 sep;117(3):686-9
stira [4]

A form of neuraxial anesthesia known as spinal anesthesia involves injecting local anesthetic (LA) into the cerebrospinal fluid (CSF) of the lumbar spine in order to numb the nerves that leave the spinal cord.

<h3>What does the study indicate?</h3>
  • As long as there is no indwelling epidural catheter or neuraxial anesthesia contraindication, spinal anesthesia is generally regarded as a reasonable anesthetic choice for cesarean delivery in severe preeclampsia.
  • Those with severe preeclampsia experience spinal-induced hypotension less frequently and with less severity than healthy parturients.
  • Although spinal anesthetic may result in more hypotension than epidural anesthesia in cases of severe preeclampsia, this hypotension is often manageable, transient, and unrelated to clinically meaningful differences in outcomes.

Explanation:

1. Mitochondria: It is the powerhouses of a cell oval in shape found in eukaryotic cell.Its a site of cellular respiration. It converts glucose in chemical energy known as ATP (Adenosine triphosphate). ATP provides energy to carry out cellular function by breaking high energy bond.Mitochondria are abundant in cells requires energy to perform functions such as muscle and liver cells.

2. Chloroplast: In plants and algae chloroplast is a site of photosynthesis,it contains a pigment chlorophyll which captures energy from sunlight and turn water and carbon dioxide into glucose as food of plants.
