Line t passes through (4, 5) and is perpendicular to the line shown on the coordinate grid.
a coordinate plane with a line passing through two points at 0 comma 3 and 7 comma 2
What is the equation of line t in standard form?
x − 7y = −161
7x − y = 23
−7x − y = 23
x + 7y = 161
Answer:
it is b
Explanation:
The equation of line t is [tex]7x-y=23[/tex]
Equation of line :Given that , A line passing through two points [tex](0,3),(7,2)[/tex]
Slope of line is,
[tex]m=\frac{2-3}{7-0}=-\frac{1}{7}[/tex]
Since, line [tex]t[/tex] and given line are perpendicular to each other.
Slope of line [tex]t[/tex] is, [tex]=7[/tex]
Equation of line [tex]t[/tex] is, [tex]y=7x+c[/tex]
Line [tex]t[/tex] passes through [tex](4, 5)[/tex]
Substitute point in equation of line [tex]t[/tex].
[tex]5=28+c\\\\c=-23[/tex]
Equation of line [tex]t[/tex] become, [tex]y=7x-23[/tex]

ENJOY groovie DAYHow do limiting factors impact local ecosystems?
A)Limiting Factors prevent populations in ecosystems form growing any larger. If any of the limiting factors change, animal and plant populations change, too.
B)Limiting factors do not prevent populations in ecosystems from growing any larger. If any of the limiting factors change, animal and plant populations do not change, too.
C)Limiting factors can never impact ecosystems.
D)As biodiversity of an ecosystem increases, the ability to withstand environmental stress due to the loss of a single species or group also increases, improving the sustainability of the ecosystem.
Answer:
limiting factors like the availability of food, water, shelter and space can change animal and plant populations. Other limiting factors, like competition for resources, predation and disease can also impact populations. ... Sometimes a population will grow too large for the environment to support.

Arctic ice retreat is threatening many species in this ecosystem. Their resources are being cut and they are needing to find new ways to survive. Do you think in your lifetime you will see drastic effects to the species in this ecosystem and why? Will that affect other ecosystems?
Answer:
no
Explanation:because they will find new ways to survive in the environment
Answer:
We are already seeing drastic effects to the ecosystem and it's wide assortment of species. Animals such as polar bears, and seals are losing their breeding and hunting grounds. Polar bears in particular are losing their ways to catch seals for food and interbreeding with grizzly bears. Fish and whales from warmer parts of the world are starting to move up north and are becoming invasive. Most importantly, since cold water from the melting ice are mixing with ocean currents, global climates and weather systems are changing course. Ultimately, in about 500 years, there could be a large Global Climatic Shift that may put us into another Ice Age.

Explanation:
Which of these locations is most likely to experience moderate climate throughout the year?
Answer:
b
Explanation:
The location that is most likely to experience moderate climate throughout the year is C.
The location C of the map will experience moderate climate because it is a coastal region of the map.
Moderate climate weather is described as a weather condition that occurs during the day, as cool air from sea rush towards the land and during night, as cool air from the land rush towards sea.
Because location C is a coastal region which means that the location is surrounded by land which better absorbs and radiates heat much faster than sea.
Therefore, the location that is most likely to experience moderate climate throughout the year is C.

evolution by natural selection has been in effect for millions of
years?
Fossils found in higher layers of rock are older than those
found in lower layers.
Fossils found in lower layers of rock are more complex than
those found in higher layers.
© Fossils of current species have been found throughout rock
layers that are billions of years old.
0 Fossils of species that no longer exist but are ancestors of
current species have been found in rock layers.
Fossils of species that no longer exist but are ancestors of current species have been found in rock layers. Thus, the correct option is D.
What are Fossil fuels?A fossil fuel is a hydrocarbon-containing material which is formed naturally in the Earth's crust from the remains of dead organisms such as plants and animals which are extracted and burned as a fuel. The main fossil fuels which are present in the earth's crust include coal, oil, and natural gas.
The evolution of species is easily confirmed by the presence of fossils of the most diverse species of the living beings in the world. This is because, fossils are the records of species which do not currently exist, however there are existed millions of years ago and are similar to the current species, being their ancestors.
Therefore, the correct option is D.

Gregor Mendel crosses a true-breeding tall plants (TT) with a true-breeding short plant (tt). What are the predicted phenotypes for the offspring ?
a. all tall
b. all short
c. ratio of 1 tall : 1 short
d. ratio of 3 tall : 1 short
Answer:
a. all tall:
Explanation:
Tall plants (TT) are the more dominate trait. Use the Pundett square (I will try to recreate it as best as possible but it will not look good):
t t
T Tt Tt
T Tt Tt
As you can (kind of) tell, T appears on all offsprings, and as the dominate trait, it will take over 100% of the time.
The next generation (depending on who you are breeding them with), will have a different result.

State reason(s) why ash should or should not be used in making compost
Answer:
Fireplace ashes for compost can be used to help maintain the neutral condition of the compost. It can also add nutrients to the soil. Decomposing materials in the compost pile can become somewhat acidic and wood ash can help offset this, as it's more alkaline in nature. But Adding too much ash to the pile can be detrimental to the makeup of the compost because of its alkalinity. Ashes tend to raise the soil pH, so you shouldn't use it directly on plants, especially acid-loving ones like rhododendrons, azaleas, and blueberries. Also, in high amounts, wood ash can inhibit plant growth by restricting nutrients, like iron.
