Describe an adaptation to a plant's life cycle and explain how this adaptation helps the plant survive. Source StylesNormal
Answer:
The adaptation of a plant in an environment ( for example,desert) depends on the structural parts of the plant which enables it to complete it's life cycle.
Explanation:
Plants are found in different types of environment. They need to possess and show some features that will enable them to live successfully and reproduce in that particular environment. Such features may be structural, functional or behavioural which are known as ADAPTATIONS.
Furthermore, in environment where there is scarcity of water supply, plants known as xerophytes can survive or thrive. They show the following adaptations:
--> well developed roots: the roots grow down to great depths if necessary and branch extensively in order to absorb water from as large an area as possible.
--> presence of swollen stems: These stems contains water storage cells which are called succulents. They help the plant withstand long period of drought.
--> Reduced leaves: This helps in reducing water loss from leaves through transpiration. For example in plants like the cacti, the leaves are reduced to spines.
Therefore, these structures helps the plant survive in its present environment.

A. liquid at room temperature
B. animal fats

D. not fully saturated with hydrogens
Answer:
C
Explanation:
Whoever gets it right i will mark brainest
Answer:
For Desssert: C
For Taiga: A
For Tropical Rainforest: B
Explanation: Because desserts are very hot, we know that there aren't much plants due to the lack of rain/water, they're dry. Rainforests have lots of plants, so it's not B, and since the dessert is high temperature, A is obviously off the list.
Taiga is cold so it won't be good for soil and the plants won't grow as good as the wet rainforest so we can pick A. Then B for #2

Experiments have shown that adult human hearing is most sensitive in the frequency range of the sound of a human baby crying. Based on the threshold of audibility curve shown for an adult male shown below, into which frequency range does most babies' crying fall? Threshold of audibility equal-loudness curve A. 25 – 50 Hz B. 250 – 500 Hz C. 2500 – 5000 Hz D. 10,000 – 20,000 Hz
Answer:
The correct answer is - C. 2500 - 5000 Hz
Explanation:
According to the graph, there is the threshold of audibility curve that exhibits that at 2500 Hz and 5000 Hz, the lowest thresholds of audibility are present. So the sound that is faintest can be heard at 2500 Hz and 5000 Hz.
This is the reason that te humans are sensitive to the crying of the babies as they must cry at 2500 Hz and 5000 Hz frequency and we get their attention easily.

why does a male body produce more testosterone than a female's body
Answer:
Levels depend on a person's age, sex, and health. Males usually have much higher levels of testosterone in their body than females
Explanation:
As the metabolism of testosterone in males is more pronounced, the daily production is about 20 times greater in men. Females are also more sensitive to the hormone

Commensalism is a symbiotic relationship in which one organism benefits and the other organism neither benefits nor is harmed.
Mutualism is a symbiotic relationship in which both organisms benefit.
Parasitism is a symbiotic relationship in which one organism benefits and the other organism is harmed.
Predation is a relationship in which one organism preys on (and eats) another organism.
Competition is relationship in which two organisms must fight (directly or indirectly) for resource
Objective:
Given a description of the relationship between two organisms, determine if their relationship is competition, commensalism, predation, mutualism, or parasitism.

I WILL GIVE YOU BRAINLIEST
Answer:
Most cells in our body have two versions of each chromosome (Body cells). These cells are called diploid. We grow and replace these cells with identical cells through a cell division called mitosis.
For sexual reproduction, we need to make cells that have only one version of each chromosome (sex cells). These cells are called haploid. These unique cells are made through a cell division called meiosis.
Explanation:
haploid = 1
diploid= 2 // "di"=2
our body contains 46 chromosomes, half from our dad and a half from our mom. our repoductive contains 23 chromosomes.
3. Compare and contrast the movement produced by each of the three types
Answer:
strike-slip is when the blocks have mostly moved horizontally, normal is when a dip-slip fault in which the block above the fault has moved downward relative to the block below, and thrust is when the hanging wall moves up relative to the footwall.
There are three faults. Normal faults originate from the divergent boundary. Reverse faults originate from the convergent boundary. Strike-slip fault originate from transforming boundary.
What are the three types of fault?We can differenciate three types of faults,
Normal fault ⇒ originate from divergent movementReverse fault ⇒ originate from convergent movementStricke-slip fault ⇒ originate from transforming movementWhat are the boundary types?I. Divergent:
This boundary occurs when two plates separate and molten material rises from the mantle creating a new crust.
The hot material creates a new seabed between the separating plates, expanding the sea bottom.
II. Convergent.
Collision area between two plates. Two oceanic plates might collide, or one oceanic plate with a continental one.
In this last case, the oceanic crust sinks under the continental plate, and magma rises to the surface by crevices.
The thicker and older plate subduces under the other plate.
III. Transforming.
The plates slide laterally with each other, and they are usually called faults.
It is associated, in general, with the oceanic ridge, although it might also occur in the continental plate.
No rocky material is either destroyed or formed.
When the plates move and produce a displacement of one transforming limits from side to side, earthquakes occur.
The movement breaks the crust and originates pronounced fractures.
