Answer:
red blood cells, which contain no DNA in their mature state, and some immune system cells that rearrange their DNA while producing antibodies
Cell is the basic unit of life and they contain the needed information known as the DNA (genetic material) to carry out the basic life functions and processes.
All cells in the body essentially have the same genome except some red blood cells and some immune cells.
Red blood cells do not contain as DNA as they lack a nucleus so they are an exception to the rule. While some immune cells needs to reassemble their genome in order to aid in the production of antibodies.
Actually, gene expression comes in with this because cells become different as a result of the fact that a cell can decide which gene is to be expressed or not in accordance to its function it is supposed to perform.

What is sun ? Pls answer me
The Sun is a star. It is a huge, spinning, glowing sphere of hot gas. The Sun is just like the stars that you see in the night sky. ... The Sun is the center of our Solar System and contains most of the mass in the Solar System. All of the planets in our Solar System, including Earth, orbit around the Sun.
Answer: The Sun is the star at the center of the Solar System. It is a nearly perfect sphere of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy mainly as visible light and infrared radiation.

What powers the carbon cycle?
Answer:
[tex] \: [/tex]
Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas.
Answer:
The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Carbon is the main component of biological compounds as well as a major component of many minerals such as limestone. Along with the nitrogen cycle and the water cycle, the carbon cycle comprises a sequence of events that are key to make Earth capable of sustaining life. It describes the movement of carbon as it is recycled and reused throughout the biosphere, as well as long-term processes of carbon sequestration to and release from carbon sinks. Carbon sinks in the land and the ocean each currently take up about one-quarter of anthropogenic carbon emissions each year.

The movement of small organic molecules, electrolytes, vitamins, and water across the digestive epithelium and into the intestinal fluid of the digestive tract is called what then? I can understand if going into the interstitial fluid of the digestive tract that it would be called Absorption; however, what is it called when it moves into the intestinal fluid of the digestive tract?
Answer:
As you have learned, the process of mechanical digestion is relatively simple. It involves the physical breakdown of food but does not alter its chemical makeup. Chemical digestion, on the other hand, is a complex process that reduces food into its chemical building blocks, which are then absorbed to nourish the cells of the body. In this section, you will look more closely at the processes of chemical digestion and absorption.
This diagram identifies the functions of mechanical and chemical digestion and absorption at each organ. Next to each organ, a callout identifies which steps of digestion take place in that particular organ.

Bones are organs composed of hard living tissue providing structural support to the body – it's scaffolding. It is a hard matrix of calcium salts deposited around protein fibers. Minerals make bone rigid and proteins (collagen) provide strength and elasticity. ... The outer layer of bone is called Cortical bone.
Which pair of triangles can be proven congruent by SAS?
Answer:
Explanation:
The seconded one
The second triangle can be proven congruent by SAS (side-angle-side). Therefore, option B is correct.
What is SAS property?SAS stands for "Side-Angle-Side" and it is a property of congruent triangles. This property states that if two triangles have two pairs of corresponding sides that are proportional and the included angles between those sides are congruent, then the triangles are congruent.
In other words, if two triangles have the same length of two sides and the angles formed by these sides are the same, then the triangles are congruent.
This property is one of several ways to prove that two triangles are congruent, and it is a useful tool in geometry and trigonometry. The other ways to prove the congruence of triangles are SSS (Side-Side-Side), ASA (Angle-Side-Angle), AAS (Angle-Angle-Side), and HL (Hypotenuse-Leg) properties. Hence, option B is correct.

Answer:
What does it mean to be 'alive'? At a basic level, viruses are proteins and genetic material that survive and replicate within their environment, inside another life form. In the absence of their host, viruses are unable to replicate and many are unable to survive for long in the extracellular environment.

Choose which assumption must be made in order for this estimate of broad-sense heritability to be correct.
a. The phenotypic variance of the genetically identical plants is the same as the genetically variable population.
b. The genetic variance component is strictly the result of additive genetic variance.
c. The environmental variance of the genetically identical plants is the same as that of the genetically variable population.
d. There is no phenotypic variance associated with the environment.
The assumption 'environmental variance of the genetically identical plants is the same as that of the genetically variable population' is CORRECT. It is used to estimate the variation due to genetic factors.
Heritability (h2) refers to the proportion of the variability of a given phenotypic trait due to genetic factors.
Broad-sense heritability is affected by genetic and environmental factors.
Broad-sense heritability can be estimated as H² = VG/VP, where VG and VP represent genetic variability and phenotypic variability, respectively.
