A musk ox and the Alstroemeria flower have physical structures and organs that have similar functions. Provide two examples of similar structures or organs and describe how they have similar functions.

Answers

Mamalas

The organs which perform same function and looks but they are different in their structure from each other are called as analogous organs.
Organs are the structures that made up of two or more tissues organized to carry out a particular function.
An organ or bone that appears in different animals with the same function is called homologous structure.
Homologous organs have similar origin n basic structure but perform different functions in different organisms. Analogous organs are different in basic structure but perform same functions.

Examples :
The arm of a human,the wing of a bird or a B at, the leg of a dog and the flipper of a dolphin or whale are homologous structures.


The forelimbs of all mammals have the same basic bone structure. The structures are all similar because they envolved to do the same job.

HOW DOES STRESS AFFECT YOUR FOCUS???
Hint: The shallower our breath, the less oxygen that reaches our brain, and the harder it is to focus.
1: When you are stressed you start breathing more deeply and makes it harder to focus.
2: When you are stressed more oxygen gets to your brain and makes it harder to focus.
3. When you are stressed you start breathing more deeply and that delivers more oxygen to your brain helps you focus.
4. none of these

Answers

Answer:

Ironically, stress does improve concentration for a very short period of time. This is due to the body releasing chemicals into the brain to help it focus and pushing adrenaline into the bloodstream in order to heighten the senses, which helps the body hone in and focus on tasks at hand.

What is the goal of Meiosis 1?

Answers

Answer:

In meiosis I, chromosomes in a diploid cell resegregate, producing four haploid daughter cells

Answer:

Meiosis I is the reduction division, and meiosis II is more similar to mitosis in that the sister chromatids are separated. The goal of meiosis I is to separate homologous chromosomes. The goal of meiosis II is to separate sister chromatids. In meiosis II, no DNA is duplicated as in prophase I of meiosis I.

Which of these best describes how the lungs and diaphragm affect each other?

A
As the lungs expand, the diaphragm expands.

B
As the lungs expand, the diaphragm contracts.

C
As the lungs contract, the diaphragm contracts.

D
The lungs and diaphragm have no relationship.

Answers

A seems like the best answer, since your lungs expand while you breath it makes sense that the diaphragm would expand.
b, because when the lungs expands it pretty much takes up space in the diaphragm making a contract

Why do roots always grow in a downward direction, no matter which way you turn the seed or seedling?
because roots weigh more than any other plant part
because the plant’s stem begins to grow, and it pushes the roots downward
because that is the direction that roots find necessary water and nutrients
because the root contains hormones that make it grow away from the sun

What is the problem with using common names in classification?

Answers

A general phobia with unfamiliar latinized scientific nomenclature has proliferated the use of common or trivial names. These names, however, can vary with geographic region, language, or individual preference often and thus, can lead to misidentification or a delay in the proper identification of a toxic plant.

Answer:

The only problem of using common names is that we cannot deduce the features of a particular organism just by looking at its name.

Explanation:

The only problem of utilizing basic names is that we can't find the highlights of a specific organic entity just by seeing its name.
