Biology
1 answer:
mariarad [96]3 years ago
8 0

Answer:

Hydrogen bonds tend to be weaker than covalent or ionic bonds. The hydrogen bond formed between water molecules has a dissociation energy of 0.24 eV. A hydrogen bond has is approximately 90% ionic and 10% covalent. Van der Waals bonds are weak bonds with a dissociation energy of about 0.01 eV.

The drug colchicine inhibits the formation of spindle fibers during mitosis. If you treat dividing plant cells with colchicine,
vekshin1

Answer:

D

Explanation:

During metaphase of cell division, the chromosomes line up in the metaphase plate and the spindle fibers from the poles extend and attach to the centromeres of the chromosomes. The spindle then contracts and pull different chromosomes to the opposite poles of the cell before the parent cell divides.   If spindle fibers do not form, then the chromosomes will not separate during anaphase.

Therefore, the final cell after mitosis will be a cell with double the number of chromosomes -because if you remember, during interphase, genetic material is replicated so each daughter cell can have its copy-. Due to quality control in the process of cell divisison, this cell will mostly undergo apoptosis, otherwise, it could develop into cancer.

State one effect the reintroduction of the
Natali [406]

We can confirm that the reintroduction of the wolf to the ecosystem would most likely cause a decline in the population of coyotes.

<h3>Why would this cause a decline in the population of coyotes?</h3>

The wolf, in most ecosystems, is considered to be the top predator. This means that it will also hunt and consume the coyotes. This alone would cause a decline in the coyote population as they now have an additional predator hunting them. Also, the wolves would be competing with the coyotes for food sources, furthering the impact on the coyote population.

Therefore, we can confirm that the reintroduction of the wolf to the ecosystem would most likely cause a decline in the population of coyotes.

Mendel also wondered if the inheritance of one trait affected the inheritance
svet-max [94.6K]

Answer:

A. dihybrid crosses

Explanation:

A dihybrid cross can be defined as a mating experiment between two lines/varieties/organisms that differ in two phenotypic traits. By using pea plants, Mendel performed dihybrid crosses in order to analyze the mode of inheritance of both phenotypic traits at the same time. From these mating experiments, Mendel observed that the inheritance factors (nowadays called genes) sorted independently from one another in the next generation, which is called the principle/law of Independent Assortment.
