what is an organism that usually has one cell and does not have organelles

The nitrogenous bases found in DNA but not RNA are thymine (T) and deoxyribose (dR).

DNA (deoxyribonucleic acid) contains four nitrogenous bases: adenine (A), cytosine (C), guanine (G), and thymine (T). Thymine is unique to DNA and pairs specifically with adenine through hydrogen bonds in the DNA double helix structure.

On the other hand, RNA (ribonucleic acid) contains the nitrogenous bases adenine (A), cytosine (C), guanine (G), and uracil (U). Uracil replaces thymine in RNA and pairs with adenine during RNA synthesis and protein synthesis.

Therefore, thymine is the nitrogenous base that is specifically found in DNA and not in RNA.

Answer: Primary succession is succession that begins in an area w/no remnants of an older community.

Explanation:

Answer:

A. 20%

Explanation:

A DNA molecule consists of four nucleotides viz: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). According to Chargaff in his complementary base pairing rule, these nucleotides pair with one another in such a way that A bonds to T, while G bonds to C.

Based on Chargaff's rule, the amount of Adenine in the DNA is equal to the amount of Thymine while the amount of Guanine is equal to that of Cytosine i.e. A=T, G=C.

A + T + G + C = 100%

Hence, in this question, a scientist finds that 20% of the strands bases are Thymine. This means that the amount of Thymine in that DNA will also be 20%. S

Since A=T = 20% in accordance to Chargaff rule.

Answer:

Absorption: The process of absorbing nutrients occurs primarily in the small intestine. Once the food is broken down into smaller molecules through digestion, these molecules are absorbed into the bloodstream. For example, carbohydrates are broken down into simple sugars, proteins into amino acids, and fats into fatty acids and glycerol.

Circulatory System: The circulatory system, composed of the heart, blood vessels, and blood, plays a crucial role in transporting absorbed nutrients. The blood vessels form an extensive network that reaches all tissues and organs in the body.

Hepatic Portal System: After absorption, most of the nutrients are transported to the liver through a specialized system called the hepatic portal system. This system ensures that the liver, which performs various metabolic functions, receives a concentrated supply of nutrients before they are distributed throughout the body.

Bloodstream Transport: Once in the bloodstream, nutrients are carried by the plasma, the liquid component of blood. Different nutrients use specific mechanisms for transport:

Glucose: It is transported by facilitated diffusion or active transport, depending on the concentration gradient, with the help of insulin.

Amino Acids: They are transported through the bloodstream by specific carrier proteins.

Fats: Dietary fats are initially packaged into structures called chylomicrons and transported through the lymphatic system before entering the bloodstream. Once in the bloodstream, fats are carried by lipoproteins such as low-density lipoprotein (LDL) and high-density lipoprotein (HDL).

Distribution to Tissues: As the blood circulates, nutrients are distributed to various tissues and organs according to their specific needs. Nutrients are delivered to cells through the capillaries, the smallest blood vessels in the body, which have thin walls that allow for the efficient exchange of nutrients and waste products.

Cellular Uptake: Nutrients are taken up by cells through various mechanisms. For instance, glucose enters cells with the help of insulin, while amino acids are transported into cells through specific carrier proteins. Fats are taken up by cells through receptor-mediated endocytosis or by diffusion.

Metabolism: Once inside the cells, nutrients undergo metabolic processes to produce energy or build new molecules. Glucose, for example, can be metabolized through glycolysis, the Krebs cycle, and oxidative phosphorylation to generate ATP, the cell's energy currency.

Waste Removal: Metabolic byproducts, such as carbon dioxide and urea, are generated during nutrient metabolism. These waste products are transported back into the bloodstream and eventually eliminated from the body through the lungs (carbon dioxide) or the kidneys (urea).

It's important to note that different nutrients may have different transport mechanisms and pathways. The body's ability to efficiently transport and utilize absorbed nutrients is vital for maintaining proper functioning and overall health.

Answer: Sea anemone and ctenophore both inherited tentacles from a shared ancestor population, but this population separated into different environments. In each environment, different types of tentacles evolved, which helped the populations survive.

Explanation:

most likely explains why both species have tentacles and why the tentacles are different is because sea anemone and ctenophore both inherited tentacles from a shared ancestor,

Then, this population separated into different environments and there was tye evolvement of different types of tentacles evolved, which therefore helped the populations survive.

Age is an example of a nominal and discrete measure. It classifies individuals into distinct categories based on the number of years they have lived, but it does not have any inherent numerical meaning or allow for intermediate values.

Age is an example of a nominal measure. A nominal measure is a type of measurement scale that classifies data into distinct categories or groups. In the case of age, individuals are categorized into specific age groups, such as 0-18, 19-30, 31-45, and so on. These categories do not have any inherent numerical or quantitative meaning. Instead, they serve as labels to differentiate different age ranges.

Unlike a biological measure, which refers to physical characteristics of living organisms, age is not directly related to an individual's biology. It is a social construct that is used to determine the number of years a person has lived since birth. Age can be measured using a variety of units, such as years, months, or days.

Age is also a discrete measure because it takes on specific, separate values. For example, someone can be 15 years old, 25 years old, or 40 years old. There is no intermediate value between these discrete age categories.

On the other hand, age is not a continuous measure. A continuous measure is one that can take on any value within a certain range. For example, height or weight can have any value within a specific range. In the case of age, there are distinct categories and no intermediate values. You are either in one age group or another.

Comparing glenohumeral and Femoroacetabular joints: a. the Femoroacetabular joint has a larger labrum.

The glenohumeral joint, which consists of a complex, dynamic articulation between the proximal humerus and the glenoid of the scapula, is a ball-and-socket joint. Particularly, the glenoid cavity (or fossa) of the scapula is in touch with the head of the humerus.

The hip joint, also known as the femoroacetabular joint, is a ball-and-socket joint that connects the femur, the thighbone, to the pelvis. The socket, also known as the acetabulum, is formed by the pelvic bone's hollow and the upper portion ("head") of the femur, a round ball.

The 5ꞌ end of a DNA strand always has a free phosphate group while the 3ꞌ end always has a free hydroxyl group. Deoxyribonucleic acid, or DNA, is a double-stranded molecule made up of nucleotide building blocks. Each nucleotide is made up of a nitrogenous base, a deoxyribose sugar, and a phosphate group.

The nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G). These bases pair up to form base pairs, which are held together by hydrogen bonds. Specifically, A pairs with T, and C pairs with G. DNA strands have a directionality, with one end referred to as the 5ꞌ end and the other as the 3ꞌ end. The 5ꞌ end of the DNA strand is where the phosphate group is bound to the 5ꞌ carbon of the sugar, while the 3ꞌ end is where the hydroxyl group is bound to the 3ꞌ carbon of the sugar. These free phosphate and hydroxyl groups are critical for the formation of phosphodiester bonds between adjacent nucleotides.
