A. Habitat loss
Because by farming the land, species living within the environment loose areas to live in which decreases biodiversity.

B. Eutrophication
Because when using lots of fertilizer, it will eventually lead to run off during rain and the fertilizer will end up in the lakes which affects the biodiversity there. And to define eutrophication, it's basically just the increase of nutrients in lakes or a body of water. This can lead to overgrowth of aquatic plants and they will take up more oxygen and release carbon dioxide which will end up suffocating the aquatic animals living within the water

Answer:

  • time: 1.122 seconds
  • range: 10.693 m
  • maximum height: 1.543 m

Explanation:

<u>Given</u>:

  runner is launched at 30° angle to horizontal at 11 m/s

  acceleration due to gravity is g = -9.8 m/s²

<u>Find</u>:

  runner's hang time

  runner's distance to the landing point

  runner's maximum height

<u>Solution</u>:

The (horizontal, vertical) speed components will be ...

  (11 m/s)(cos(30°), sin(30°)) = (5.5√3 m/s, 5.5 m/s)

The time of flight can be found from the height formula:

  h(t) = 1/2gt² +vt . . . . . . where v is the vertical speed at launch

The time we're concerned with is the time when h(t)=0 and t>0.

  0 = -4.9t^2 +5.5√3t = t(-4.9t +5.5√3)

The second factor is zero when ...

  t = (5.5√3)/4.9 ≈ 1.122 . . . seconds hang time

__

The distance to the landing point will be the product of horizontal speed and hang time:

  d = (5.5 m/s)(5.5√3/4.9 s) ≈ 10.693 m . . . . distance to landing

__

The maximum height can be found from the formula (based on conversion of kinetic energy to potential energy) ...

  h = v²/|2g| = (5.5 m/s)²/(2(9.8 m/s²)) ≈ 1.543 m . . . . maximum height

A scientist is studying the inheritance of two characteristics in plants: red flowers (RR and Rr) , which are dominant to yellow
marin [14]

Answer:

The correct option is <em>B. Crossing- over </em>

Explanation:

In biology, crossing over can be described as a phenomenon by which homologous chromosomes exchange segments during the process of meiosis.

The unexpected results came because the DNA segment between the homologous chromosomes was exchanged during meiosis. The alleles got shuffled by this process and hence showed the unexpected results.

Crossing over and independent assortment are phenomenon which occurs only during the process of meiosis. These phenomenons cannot be observed during mitosis.

Where does the fertilized egg grow and develop while a woman is pregnant
Scilla [17]

Answer: Uterus

Explanation:

A fertilized egg is called ZYGOTE, and it is the product of fusion between a sperm cell and ovum cell.

The zygote is attached and housed in a muscular organ known as Uterus, commonly referred to as Womb. Here, the zygote grows and develops for several weeks into a foetus and then a human child (baby) in the pregnant woman
