Answer:

There are many ways in which a plant can adapt itself to cold winters.

Step-by-step explanation:

   Adaptation is the ways an organism can obtain what ir needs despite the sorrounding environment. Plants adapt themselves to be able to suit a cold weather. They need water to survive and they can't take it from snow or they need to prevent water from evaporating.

   Some plants drop their leaves because they evaporate water into the air. Other plants keep their leaves called needle leaves. They reduce water loss by transpiration. Some plants have a thick bark, which protects the trunk from extreme winter cold. Some others have a conical shape, which doesn't allow the snow to stay for a long time. The same happens with plants with  downward sloping branches, which allow snow to slide off more easily. Plants need to survive cold winters and their different parts help them do so.

In quadrilateral ABCD, BN and DM are drawn perpendicular to AC such that BN = DM. Prove that O is the midpoint of BD
GaryK [48]

Answer:

Step-by-step explanation:

Given :

In the given quadrilateral ABCD,

BN and DM are the perpendiculars drawn to AC such that,

BN = DM

To prove:

Point O is the midpoint of segment BD.

Or

OD = OB

Solution:

In ΔOMD and ΔONB,

∠MOD ≅ NOB [Vertical angles]

∠M ≅ ∠N ≅ 90° [Given]

Therefore, by AA property of similarity,

ΔOMD ~ Δ ONB

Therefore, their corresponding sides will be proportional,

\frac{DM}{BN}=\frac{OD}{OB}

Since BN = DM,

OD = OB

Hence O is the midpoint of BD.

Evaluate the following expression
krek1111 [17]

Answer:

1

Step-by-step explanation:

a+b divide c -> \frac{a+b}{c}

Plugging in - > \frac{2+-3}{-1}

Simplifying: \frac{2-3}{-1}

Subtracting: \frac{-1}{-1}

Simplifying: 1

Multiply.<br>(2x-5) (3x-7)​
Naya [18.7K]

Answer:

6x^2 -29 +35.

Step-by-step explanation:

use the FOIL method(First, Outer,Inner, and Last.)

2x x 3x=6x^2.

2x x -7=-14x.

-5 x 3x =-15x.

-5 x -7=35.

= 6x^2 -14x -15x+35

6x^2 -29x +35.

Plss help it's urgentt​
juin [17]

Answer:

1. 25

Step-by-step explanation:

First, you need to place the numbers in ascending order, meaning from smallest to largest.

You calculate the range by taking the largest number and subtract the smallest from it, so in this case: 42-17 = 25

Mean (average), just add the numbers up and divide by how many numbers you have

III. Once you find the Mean and you placed them in order from smallest to largest, you can find this answer

Median (middle) - which number is in the middle so after you place them in order which is in the middle if you have an odd number of marks, but since you have 12 marks then take the 2 center numbers, add them up, and divide by 2, in other words, get the mean of the middle numbers and that will give you the median in this problem

Mode, which number appears the most times repeated
