Each individual starts as a single cell - an ovum - with a full set of the species' chromosomes/DNA - in humans always 22 and an X.

How is a whale more like a human than a fish? CHOOSE ALL THAT APPLY 1.warm blooded 2.breast feeds its young 3.spends much time out of the water 4.can hold its breath for long periods of time
Answers
Answer:
1. warm blooded, 2. breast feed its young
Explanation:
Whales are warm blooded, which means they keep a high body temperature that does not change in the cold water. Fish are cold-blooded, so their body temperature changes depending on the temperature of their environment. AND hales are other mammals that feed their young milk too, although it takes plenty more to feed them than human babies
what is the best example of tropism in plants
Answers
Answer:
Explanation:
Some plants (flowers or leaves or both) follow the sun as it arcs across the sky each day; sunflowers (Figure below) are a well-known example. This behavior is misleadingly called heliotropism. Helio- does refer to the sun, but a tropism implies growth in a certain direction, and heliotropism does not involve growth.
One example is hydrotropism.

An electrocardiogram (ECG) provides information about: Group of answer choices the pressure of blood in the heart chambers the rhythm of heart contractions the speed of blood flow through the blood vessels the amount of oxygen in the blood as it leaves the heart
Answers
Answer:
the rhythm of heart contractions.
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
1. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
2. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
An electrocardiogram (ECG) provides information about the rhythm of heart contractions.
Additionally, the right atrioventricular valve (AV) also referred to as the tricuspid valve is located on the right dorsal side of the human heart. The right atrioventricular valve (AV) comprises of three (3) leaflets (flaps) which opens and closes in order to allow for the flow of blood from the right atrium of the human heart to the right ventricle. Also, the right atrioventricular valve is saddled with the responsibility of preventing blood from flowing backward in the mammalian heart.

True or False: Purine is connected to pyrimidine using oxygen bonds.
Answers
Answer:
False
Explanation:
In DNA double helix molecule, there are four types of nitrogenous bases: adenine, guanine, cytosine and thymine. Purines (i.e., adenine, guanine) and pyrimidines (i.e., cytosine and thymine) hold DNA strands together via hydrogen bonds. In base pairing, guanine always pairs with cytosine through 3 hydrogen bonds, while adenine always pairs with thymine by 2 hydrogen bonds. Hydrogen bonds are a type of dipole–dipole interaction where a hydrogen atom is covalently bonded to a very electronegative atom (e.g., Nitrogen or Oxygen).
Which type of base is shown? How can you tell?
Answers
Answer:
The correct answer is - purine nitrogenous base (adenine).
Explanation:
The base given in the diagram in the image has two rings attach with the pentose sugar which is attached to the phosphate, which means it is the diagram of nucleotide. In this nucleotide base can be either purine or pyrimidine.
Pyrimidines have a single ring structure, whereas purines have 2 ring structures. Adenine and guanine are purines with two ring structures whereas cytosine and thymine are pyrimidines as they have one ring structure. Adenine contains an amine group on C6, and a double bond between N1 and C6.
