Answer:

The traits that are transferred from the parents to the offspring during reproduction are determined by genes, located on chromosomes, found in the nucleus.

Explanation:

During reproduction, there is a fusion of;

male gamete

female gamete

This leads to the formation of offspring. There is a transfer of traits from the parents to the offspring.

Hence, the traits that are transferred from the parents to the offspring during reproduction are determined by genes, located on chromosomes, found in the nucleus.

What could a scientist do to determine what era the Eocene Period belongs to on the geologic time scale?

Burka [1]

Answer:

Option B) study information related to the Cenozoic era

Explanation:

The complete question is

Scientists discovered that the Eocene time period existed in Earths history around 34 MYA. What do they need to do to determine what time period Eocene belongs to on the geologic time scale?

A) learn what happened during Precambrian time

B) study information related to the Cenozoic era

C) view the timing of events in the Mesozoic era

D) research events that happened during the Paleozoic era

Solution -

The period of Eocene belong to the Cenozoic era. The Cenozoic era is divided into three periods-

a) The Paleogene – Existed between 65.5 to 23.03 million years ago

b) The Neogene - Existed between 23.03 to 2.6 million years ago

c) The Quaternary – Started some 2.6 million years ago and is continuing till present

The Paleogene is subdivided into three epochs –

A) The Paleocene – existed between 65.5 to 55.8 million years ago

B) The Eocene – existed between 55.8 to 33.9 million years ago and

C) The Oligocene – existed between 33.9 to 23.03 million years ago

Hence, studying about Cenozoic era will give information about the Eocene epoch

Hence, option B is correct

What is the expected colorimetric result from the negative control in your assay?

mote1985 [20]

3,3',5,5'-Tetramethylbenzidine or TMB is a chromogenic substrate visualising reagent used in enzyme-linked immunosorbent assays (ELISA), it yields a blue color when oxidized, typically as a result of oxygen radicals produced by the hydrolysis of hydrogen peroxide by HRP, (thermofisher). The expected colorimetric result from the negative control in your assay will be no development of blue color

Scientists describe a period called the Great Acceleration, in which human activities began significantly altering global system

victus00 [196]

Answer:

The invention of agriculture, advances in medical technology that have greatly reduced the human death rate and he rapid increase in the uses of fossil fuels, fertilizers, metal ores, and other resources.

Option: (A), (C) and (D)

Explanation:

The Great Acceleration refers to the humanity’s impact upon the Earth’s geology and its ecosystems caused by continual and surge in growth of human activity.

It was first recorded in mid-20th century and is continuing to this day. The 'invention of agriculture', advancement in medical technology which reduced the death rate, rapid increase in use of 'fossil fuels', 'fertilizers' and other resources contributed to global changes.

Agriculture allowed us to produce more food and population increased rapidly.

Fossil fuels created a surge in production of Green House Gases and global temperature began to rise.

navik [9.2K]

Terminal buttons.

Explanation:

Neurons are longest animal cell that serve as the basic unit of their nervous system.

The neuron is divided into two parts-

Cyton: It is the cell body of the neuron. It has projection extending from the cytoplasm that receive signals called dendrites.

Axon: It is a long process extending from the cyton that carries the impulse from cell body to end of neuron. The axon terminate at knob like structures called terminal button . These release neurotransmitter and are rich in mitochondria.
