Answer:

The lipoproteins with the highest proportion of triglyceride are CHYLOMICRONS.

Explanation:

Lipoproteins are biochemical molecules that are made up of lipid and protein; their primary function is to transport fat molecules in blood and in extracellular fluids. There are different types of lipoproteins, one good example of these are plasma lipoprotein particles, which are made up of HDL (high density lipoprotein), LDL (low density lipoprotein), VLDL (very low density lipoprotein), IDL (intermediate density lipoprotein) and ULDL (ultradensity low lipoproteins).

ULDL are also known as chylomicrons and they have the highest quantity of triglycerides.

Question 6 You cross a true-breeding red-flowered snapdragon with a true-breeding white-flowered one. All of the FI are pink. Wh

Answer:

E (Red shows incomplete dominance over white)

Explanation:

This portrays a monohybrid cross involving a single gene coding for flower colour in snapdragon plants. According to the question, a purebreeding red flowered (homozygous) plant is crossed with a purebreeding white flowered (homozygous) plant to produce an all pink flowered offspring. This phenomenon is called INCOMPLETE DOMINANCE.

Mendel, in his experiments, discovered that an allele can mask the expression of another in a heterozygous state. He called the allele that masks DOMINANT allele while the allele that is masked RECESSIVE allele. However, exceptions like INCOMPLETE DOMINANCE, has occurred in the sense that an allele does not completely mask the expression of its allelic pair, instead an intermediate phenotype, which is a combination/blending of both parental phenotypes is produced.

In this case, the red flowered snapdragon (RR) does not completely cover up the expression of white flower (rr), hence a hybrid/heterozygous offspring is produced that combines the phenotypic characteristics of both parents to form an intermediate flower colour (pink). Hence, it can be said that Red flower is incompletely dominant over white flower or no allele/trait is dominant or recessive to another.

18. Refer to Models 1 and 2 to complete the chart below. Write yes or no in the box for cach cell.

Ostrovityanka [42]

The most primitive cells are prokaryotic. They are simple, with no organelles and no nucleus. Animal and plant cells are eukaryotic, but they express some differences such as the cell wall, chloroplasts, or centrioles.

---------------------------------------------

BACTERIA CELLS

Bacteria are prokaryotic cells.

Prokaryotic cells lack a nucleus, nucleolus, and organelles.

They only present plasmids, ribosomes, and genetic material in their cytoplasm.

DNA not surrounded by membrane

They have a cell wall that protects the cell and a cell membrane that surrounds the cytoplasm. Some of them can also present a capsule.

Some of them have flagellum.

These organisms are capable of inhabiting places with extreme temperature, salinity, acidity, or pH, among others.

ANIMAL AND PLANT CELLS

Both the animal and plant cells are eukaryotic.

They carry their genetic material in the nucleus and mitochondria.

Organelles are located in the cytosol, and both of them are surrounded by a protector cell membrane.

However, they have some differences:

⇒Cell wall : A rigid structure that provides support and protection.

• Animal cells do not have a cell wall. They are only surrounded by the cell membrane, which is flexible so they can adopt different shapes.

• Plant cells have a wall, so their shape is usually prismatic and regular. The cell wall is composed mainly of cellulose.

⇒ Chloroplast: these are organelles that accumulate chlorophyll.

• Animal cells do not have chloroplasts because they do not photosynthesize.

• Plant cells have chloroplasts, and they are in charge of the photosynthesis process that allows plants to release oxygen. These organelles use solar light as the source of energy.

⇒ Vacuoles:

• Animal cells have many and small vacuoles whose function is to store water, ions, and waste intracellular substances.

• Plant cells have a unique big-sized vacuole that might occupy almost 90% of the cell. Their principal function is to store water and keep the turgidity. When the vacuole gets empty, the plant loses rigidity.

⇒ Other differences are:

The animal cell has centrioles, while the vegetable cell does not.

Plasmodium, chromoplasts, and glyoxysomes are present in the vegetable cell but not in the animal cell.

Answer:

Protecting children from exposure to lead is important to lifelong good health. No safe blood lead level in children has been identified. Even low levels of lead in blood have been shown to affect IQ, ability to pay attention, and academic achievement. And effects of lead exposure cannot be corrected.

The most important step parents, doctors, and others can take is to prevent lead exposure before it occurs .
