In later chapters, you will learn more about the regulation of gene expression. One way to regulate gene expression is to make c

hanges to the histone proteins to alter how tightly the DNA is coiled and wrapped. The more tightly coiled and wrapped a particular region of DNA is, the less likely it is that the genes in that region will be expressed. Bearing this in mind, how tightly do you think regions of heterochromatin are compacted?

Answer:

Highly condensed.

Explanation:

The different region of the eukaryotic chromosome are euchromatin region and heterochromatin region. The heterochromatin region is genetically inactive whereas euchromatin region is highly active.

The heterochromatin region is generally present at the periphery of the nucleus. This region is transcriptionally inactive. This is because of the compactness of DNA. DNA is packed very tightly or present in highly condensed form with the histones.

Thus, the answer is highly condensed.

In most animals, the ______ state of the life cycle is much larger than the ______ state.
Alexxx [7]

In most animals, the diploid state of the life cycle is much larger than the haploid state.

<h3>What is life cycle?</h3>

The life cycle of animals is the oscillation of their lives between the haploid (n) or sexual phase and the diploid (2n) or vegetative phase.

The haploid or sexual phase of animals has to do with their gametes. The male animals produce male gametes while the female animals produce female gametes.

During fertilization, the haploid male gamete (n) fuses with the haploid female gamete (n) to form a diploid (2n) zygote. The zygote is what divides mitotically to form the baby and continues to divide to form the adult animal.

For example, in humans, the female gamete is the egg while the male gamete is the sperm. The diploid version of humans is what we see every day.

Thus, when you consider it, you will see that the haploid life cycle of most animals is much bigger than their diploid life cycle.

Describe two typical applications for each of the following types of microscope
Veseljchak [2.6K]
A.Transmission electron microscopes are a versatile tool for many fields, including medicine, biology, nanotechnology, metallurgy, forensics, electronics, material science, and much more. A biologist might use a TEM to look at the internal structure of a cell.

b. Industries including microelectronics, semiconductors, medical devices, general manufacturing, insurance and litigation support, and food processing, all use scanning electron microscopy as a way to examine the surface composition of components and products.

c.Brightfield Microscope is used in several fields, from basic biology to understanding cell structures in cell Biology, Microbiology, Bacteriology to visualizing parasitic organisms in Parasitology. Most of the specimens to viewed are stained using special staining to enable visualization.

d.A dissecting microscope is used to view three-dimensional objects and larger specimens, with a maximum magnification of 100x. This type of microscope might be used to study external features on an object or to examine structures not easily mounted onto flat slides.
