Create a food chain that contains four organisms from a producer through three consumers using corn, rabbit, grass, wolf, snake, eagle, grasshopper, Fox, rat, and hawk.
Answer:
Corn → rat → hawk → wolf
Explanation:
A food chain is a linear relationship that shows the feeding pattern of different organisms. The food chain portrays which organism located in one trophic level eats another. A forward arrow (→) is used to show that the organism after the arrow feeds on the organism before the arrow.
Every food chain starts with an organism called PRODUCER, which is capable of supplying the energy that is transferred from one organism to another. The energy moves along organisms called CONSUMERS as they feed on one another. According to this question, the below food chain shows the feeding relationship between four organisms:
Corn → rat → hawk → wolf
Note that, corn is the PRODUCER, while rat, hawk and wolf are CONSUMERS
Select ALL of the following genotypes below that respresent males.
XXY
XX
XYY
XXX
XY
Answer:
Is it XXX that all males want?
Explanation:
Just joking! I still think it is XXY
The genotype that represents males is XY of 50 % of both X and Y chromosomes where a slight change in the alignment might cause to chromosomal disorders .
XXY , XYY , XY represents males genotypes.
What are chromosomal disorders ?
These are the disorders which are associated with the change in the normal XY sequence of males. Various disorders and syndromes are associated with the mutation and the responsible factor can be trisomy like.
XXY is a chromosomal mutation found in the males only called as Jacob syndrome, XYY is a chromosomal disorder called as klinefelter syndrome found in males only.
XX is the genotype of a female, XXX is a condition that affects 1 in every 1000 females.
Thus, except XX and XXX is the exception as both of these represent females.

B. Tap roots have a root cap and undergo primary growth, fibrous roots lack a root cap and undergo
secondary growth
C. monocots have fibrous roots, dicots have tap roots
D. monocots have tap roots, dicots have fibrous roots
Answer:

Explanation:
Describe an adaptation to a plant's physical characteristic and explain how this adaptation helps the plant survive.
The development of stomata that are closed in arid conditions is an adaptation in plants. It allows plants to survive.
What is evolution?Evolution can be defined as descendence with modification, a process that involves natural selection.
Natural selection refers to the differential survival and reproduction of the more adapted organisms in a population.
Adaptations are specific features that allow organisms to have higher fitness in a population.
Stomata are structures for the interchange of gases (CO2 and O2) from the environment and can be closed to avoid water loss.

Why are lichens a good pioneer species after a volcanic eruption?
a - They are able to grow on moist soil.
b - They are able to grow on bare rock.
c - They are able to attract animals.
d - They are able to grow without water.
Plants, like all organisms, adapt to the conditions of their environment. Some special challenges a plant may face are drought, flooding, and a salty environment. Your task is to identify and describe ways that plants adapt to these challenging conditions in their environment. Select one plant adaptation to drought, one adaptation to flooding, and one for salt tolerance. Explain how each adaptation enhances plant survival. Identify a scholarly source of information for each. Use quotes appropriately; be sure your responses are written in your own words
Answer:
Hydrophytes is flood tolerant plants, barley is salt tolerant crop and sorghum is a drought tolerant crop.
Explanation:
Hydrophytes also known as flood tolerant plants that have adaptations to survive flood problems. The plant has the development of air spaces in the roots and stems which allow diffusion of oxygen from the aerial portions of the plant into the roots. Barley shows a greater degree of salt tolerance by applying method of osmoregulation which helps the plant to tolerate salt stress. Sorghum is a plant that is adapted to drought condition. These plants have less number of stomata and waxy layers on the leaves which lowers the rate of evaporation or transpiration.
if you were to design an organism, what 3 organ systems would be the most important to include?
A female guinea pig that was pure-breeding for white fur, mated with a male guinea pig
that was pure-breeding for brown fur.
All the offspring had brown fur.
One of the male offspring mated with a female with white fur.
What proportion of white offspring would be expected from this cross?
one half
none
one third
O one quarter
Answer:
one half
Because they both were pure breed (bb and BB) and all the offspring came out as brown that means that brown is the dominant trait. So the offspring are all Bb and if the offspring mated with a white fur she would have to be bb meaning their children woild be either Bb or bb

A 15 mL sample of gasoline has a mass of 11 g. What is the density of the gasoline?
The density of gasoline with a mass of 11g and volume of 15mL is 0.733g/mL.
DENSITY:The density of a substance can be calculated by dividing the mass of the substance by its volume. That is;Density = mass ÷ volume
According to this question, a 15 mL sample of gasoline has a mass of 11 g. The density of gasoline is calculated as follows:Density = 11g ÷ 15mL
Density = 0.733g/mL
Therefore, the density of gasoline with a mass of 11g and volume of 15mL is 0.733g/mL.

.Explicati de ce algele pluricelulare au culoarea rosie,verde respectiv bruna ?
Answer:
Due to different pigments.
Explanation:
The multicellular algae are red, green and brown because of the presence of pigments. The red algae are red in colour because of the presence of the phycoerythrin which is a type of pigment. This pigment reflects red light due to already presence in its body and absorbs blue light that is necessary for photosynthesis process. The brown algae contain fucoxanthin pigment and green algae contain xanthophylls pigments that are responsible for its colour so we can conclude that these different types of pigments are responsible for the different colour of algae.

a, a permanent thermocline traps nutrients in the deep water
b. primary productivity is high all year round, because there is a constant supply of solar energy for
photosynthesis
c, the thermocline disappears in the winter
d. the upper and lower layers of water mix all year round
Answer:
a, a permanent thermocline traps nutrients in the deep water
b. primary productivity is high all year round, because there is a constant supply of solar energy for photosynthesis.
Explanation:
Thermocline occurs in the tropical regions because the temperature is very high which warms the upper layer of water bodies whereas the lower layer of water has low temperature due to no sunlight. The primary productivity is high all year in the tropical regions, because there is a constant supply of sunlight that is needed by the plants for preparing their own food.

What is an example of weathering, erosion, and deposition in Texas? (A)Gradual change to Guadalupe Peak (B)All of the above (C)The changing coastline of Texas (D)The creation of Palo Duro Canyon
Answer: Weathering, erosion, and deposition from the terrestrial surface topography and soil characteristics. These processes, for example, have formed a variety of landforms in Texas like beaches, plateaus, mountains, and canyons as well as soil types like fertile soil, clay-rich soil, and sandy soil. The combination of topography, soil, and climatic conditions in an area defines the types of habitats that the area can support this is crucial to ecoregion classification. Ten separate ecoregions occur in Texas including 1) East Texas Pineywoods, 2) Gulf Coast Prairies and Marshes, 3) Oak Woods and Prairies, 4) Blackland Prairie, 5) cross timbers and prairies (6) Rolling Plains, (7) High Plains, (8) TransPecos, (9) South Texas Plains, (Brush Country), and (10) Edwards Plateau. Such ecoregions are named for the major types of habitats topographical features (e.g. Edwards Plateau) present in their areas. The weathering, erosion, and deposition of each of these ecoregions have an important influence. Hope This Helps :)
Answer:
all the above
Explanation:
weathered soil and rock from the ecoregion is eroded and deposited in the upper south Texas plains ecoregion
