Abductors enable efficient bipedal motion by contracting parts of the gluteals that attach to the ilium and allow humans to step

miss Akunina [59]

Answer:

a. True

Explanation:

Since , abductions, particularly the minimus and gluteus medius , are active on the side of the leg which is in contact with the ground . This is to avoid the tendency of gravity to cause the downward motion of the hip on the opposite side . In addition, the lateral muscle and paraspinal muscles of the trunk are active on the side of the swinging leg to avoid the downward motion of iliac crest on side .

Answer:

C is the correct answer.

Explanation:

You can automatically eliminate B and D because they have little to do with the movement of the body. And it's not A because the skeletal system doesn't have the signals to tell the muscular system what to do.

lesya692 [45]

Answer:

this is a TRUE statement.

Explanation:

Different microbes grow in a wide variety of environmental conditions; however, most have preferences for certain temperatures, pH, and atmospheric gases because although microbes are widespread in their occurrence,they are found almost everywhere,in the air,water,soil,food,decaying matter,oil deposits,in plants etc.

but their number and their types vary according to the locality and environmental conditions.

Although, some microbes are always present and contribute towards natural flora BUT besides this others are present in specific environments such as some in hot springs bearing very HIGH TEMPERATURE RANGES for example: Thermus aquaticus.

some of them inhabit the acidic or alkaline soil feeding on HUMUS.

Most of the microbes prefer ATMOSPHERIC GASES i.e some require oxygen for their survival .For example: Pseudomonas.

some don't require O2 for survival i.e Spirochete.

IN SHORT, most of the microbes have preferences for various environmental conditions.

The student should chose a location within the office that has good ventilation and a workspace big enough to accommodate all his science materials.

What is an experiment?

An experiment can be defined as a procedure carried out under supervised conditions in order to discover an unknown effect, to test or refute a claim, or to illustrate a known law.

A science experiment should be carried out in a location within the office that has good ventilation and a workspace big enough to accommodate the required science materials. The location should be devoid of children, pets and other danger-posing objects.

In conclusion, experiments are carried out in suitable conditions and environment.

Answer:

Charles Darwin

Explanation:

Natural selection, most famously proposed by Charles Darwin, states that when presented with an environmental challenge, some individuals in a species will develop adaptations to face these challenges. Successful individuals will be more likely to mate and their offspring will inherit these adaptive traits, and will continue to pass for generations.

In this sense, plants face the challenge of the cold. Those that adapt to the cold will survive and reproduce, those that can't adapt to the cold will die. Eventually, only plants that can tolerate the cold will survive.
