A water solution that has the same salt concentration as the cells is said to be _____. hypotonic isotonic

Answers

Answer 1

Answer:

The correct answer would be isotonic.

Isotonic solutions are the set of solutions which have the same concentrations of solutes.

They have same osmotic pressure across a semipermeable membrane.

The net movement of water is zero in such solutions.

Hence, the water solution that has the same salt concentration as the cells is said to be the isotonic solution.

Answer 2

Answer: A water solution that has the same salt concentration as the cells is said to be ISOTONIC.

D. military

Answers

The answers would be:

Pelvis

Coroner's office

Here is more about your questions:

The pelvis is a good identifier when it comes to male and female because the features have distinct features. The female pelvis for example is broader and the inlet is much wider. It is structured that way to prepare the woman's body for pregnancy and child birth.

Forensic anthropologists is a sub-category of anthropology. Forensic anthropologists examine skeletal remains to determine how an individual lived, died, and how long they were dead. They can also identify who they were. Forensic anthropologists can assist especially when the remains are badly decomposed.

Bone that a forensic anthropologist will analyze to identify a victim as male or female is pelvis (A).

Coroner's offices (B) most likely employs a forensic anthropologist for research.

Further Explanation:

Pelvis is a complexes of bones that links the trunk and the legs. Pelvis also has paired hipbones that are connected in front and behind at the pubic symphysis and the sacrum, respectively. The three bones are illium, ischium and the pubis. All the three bones are united at the triangular suture called as acetabulum. Female pelvis have distinct feature as it forms a ring which acts as the birth canal.

Tibia is present in the lower leg of vertebrates. It forms the lower half of the knee joint in humans.

Humerus is the upper limb long bone that forms shoulder joint above and elbow joint below present in the land vertebrate.

The sternum is a long and flat bone that act as significant part of the rib cage and helps in stabilizing the thoracic skeleton. It is also involved in protecting various vital organs of the chest.

The main role of coroner is to probe the identity of unknown individual found dead in corner jurisdiction. Forensic anthropologist inspect the skeletal remains so as to reveal how an organism lived, died and the time duration till when it was dead.

Which factor influencing flexibility is dependent upon individual behaviors?a. joint structure
b. muscle and fat
c. age
d. gender

Answers

The right answer is B muscle and fat
A: False because the joint structure does not depend on the individual behaviour, it may depend on hereditary and genetic factors.
C: false because the age is not related to the behaviour, and so the gender, they are factors that the individual cannot control

So, the right answer is muscles and fat since the individuals can control them by exercising and eating.

Muscle and fat will influencing flexibility is dependent upon individual behaviors. Option B is correct.

Flexibility is the ability of a joint or a group of joints to move through a full range of motion. It is influenced by several factors, including joint structure, muscle and fat, age, and gender. Among these factors, muscle and fat are particularly dependent upon individual behaviors.

Joint Structure: The anatomy of the joint itself, including the type of joint and the arrangement of ligaments and tendons, can influence flexibility. Some individuals may naturally have more flexible joints due to their unique joint structure.

Muscle and Fat: The length, strength, and flexibility of muscles and the amount of fat surrounding the joint area can significantly impact flexibility. Regular physical activity, stretching exercises, and conditioning of muscles can improve flexibility over time.

Age: Flexibility tends to decrease with age. As people age, their connective tissues, such as tendons and ligaments, may become less elastic, reducing joint flexibility. However, regular stretching and exercise can help maintain flexibility as one ages.

Gender: In general, women tend to be more flexible than men. This difference is partly due to physiological factors such as differences in collagen content and joint laxity between genders.

Muscle flexibility is closely related to the elasticity and length of muscles. Regular stretching exercises and activities that promote flexibility, such as yoga, can help improve muscle flexibility. Engaging in physical activities and exercises also helps reduce excess fat around the joints, which can enhance joint mobility and flexibility.

Hence, B. is the correct option.

At one time, dinosaurs lived on Earth. Today they are extinct. This relates to _____.A. microevolution
B. both macroevolution and microevolution
C. macroevolution

Answers

The answer is letter C. macroevolution. Macroevolution refers to an evolution of the largest scale, specifically creation of new species and extinction while Microevolution refers to a change in gene frequency within a population; molecular basis for evolution. The process of speciation may fall within the purview of either, depending on the forces thought to drive it.

Answer:

macroevolution

Explanation:

Despite the high-level of biodiversity, this biome has infertile soils, principally oxisols, to which the vegetation has roots systems that capture nutrients from litter decay.

Answers

The biome that has infertile soil, principally oxisols, to which the vegetation has roots systems that capture nutrients from litter decay, is the tropical rainforest.

Soil types are highly variable in the tropics and are the result of a combination of several elements or variables which includes climate, vegetation, topographic position, parent material and also the soil age. Most of the tropical soils are described by leaching and poor nutrients. It also has two classifications: namely the ultisols and oxisols. Ultisols are known as well-weathered, acidic red clays soils. They are deficient primarily in major nutrients such as potassium and calcium. Oxisols are also an acidic type of tropical soil. However, they are well drained compared to the ultisols.
