Answer:
meander
Explanation:
A meander is a series of regular sinuous curves in the channel of a stream/river/watercourse, thereby forming a rounded or "S"-shaped bend curve. Meanders are common in alluvial areas that have low gradients, where they are formed by the dynamics of the watercourse. The meander belt is the zone within which a meandering watercourse occupies on its floodplain. The sinuosity is a measure to calculate the degree of meandering in the channel of a watercourse.
the development of lateral roots is intiated by the the cork or periderm
Answer:
Because lateral roots are initiated in the pericycle and grow out through the cortex and epidermis, they are said to have an internal, or endogenous, origin, in contrast to the external, or exogenous, origin of leaves and the apical meristem of stems (see below Stems).
Explanation:
The amount of light, pressure, and temperature are examples of?
Explanation:
The answer is No. You know light from Stars travel in cold temperature of space and different pressure as they enter our planet after travelling many light year to reach us at the same the speed.
Light bends when entering a different medium(refraction). Even if the medium is same and the temperature is different it will get bend. As the 2 different temperature air behave like 2 mediums (Due to distribution of atoms ).
But light doesn't’ bend by heating or by putting pressure on it.

PLEASE HELP! I WILL GIVE BRAINLIEST. What 2 factors affect organisms and their habitats, and give examples of each
Answer:
There are two categories of these factors: abiotic and biotic. Abiotic factors are the non-living parts of the environment that can often have a major influence on living organisms. Abiotic factors include water, sunlight, oxygen, soil and temperature.
Explanation:
Biotic factors are interactions associated with living organisms. They can also influence the distribution of organisms in an ecosystem. grazing - too little leads to dominant plants outcompeting other species, too much reduces species numbers overall. Both decrease biodiversity.
Abiotic factors affect the ability of organisms to survive and reproduce. Abiotic limiting factors restrict the growth of populations. They help determine the types and numbers of organisms able to exist within an environment.

1, name the part of the reproductive system in which fertilisation happens.
2, what is an embryo
3, where does the embryo develop into a foetus, and then a baby
4, why does the uterus lining start to grow thick and spongy, as an egg cell develops in an ovary
5, what happens to the uterus lining if the egg cell is not fertilised
6, how often does an egg cell leave an ovary, in an adult woman
7, how often does menstruation happen, in an adult woman
Answer:
°•°
Explanation:
1.fallopian tube
2.an unborn or unhatched offspring in the process of development, in particular a human offspring during the period from approximately the second to the eighth week after fertilization (after which it is usually termed a fetus)
3.First, the zygote becomes a solid ball of cells. Then it becomes a hollow ball of cells called a blastocyst. Inside the uterus, the blastocyst implants in the wall of the uterus, where it develops into an embryo attached to a placenta and surrounded by fluid-filled membranes.
4.Eggs live in ovaries, and the hormones that control your menstrual cycle cause a few eggs to mature every month. When your egg is mature, it means it's ready to be fertilized by a sperm cell. These hormones also make the lining of your uterus thick and spongy, which gets your body ready for pregnancy.
5.The fertilized egg attaches to the lining of the uterus. The placenta then develops. The placenta transfers nutrition and oxygen to the fetus from mother. If the egg does not become fertilized, the lining of the uterus (endometrium) is shed during menstruation.
6.The egg cell travels down the fallopian tube into the uterus. The moment the egg cell leaves the ovary is called ovulation. Once a girl has had her first monthly period, ovulation usually occurs once a month
7.The average menstrual cycle is 28 days long. Cycles can range anywhere from 21 to 35 days in adults and from 21 to 45 days in young teens. The rise and fall of levels of hormones during the month control the menstrual cycle.

The owners of a local bakery ask for your help in improving a special yeast strain they use to make bread. They would like you to help them design experiments using RNA interference to turn off genes, to allow them to test their hypothesis that certain genes are important for the good flavors found in their bread. Of the components in the following list, which is the most important to check for in this yeast strain if you would like this project to succeed?
a. the presence of foreign double-stranded RNA
b. the presence of genes in the genome that code for RISC proteins
c. the presence of miRNA genes in the genome
d. the presence of single-stranded siRNAs within the cell
Answer:
b. the presence of genes in the genome that code for RISC proteins
Explanation:
The RNA interference (RNAi) mechanism is a naturally occurring pathway by which eukaryotic cells can silence specific genes both at the transcriptional (eg., by triggering DNA methylation on specific loci) and posttranscriptional (e.g., by triggering mRNA degradation) levels. This mechanism (RNAi) is widely used in molecular biology laboratories in order to silence genes and thus understand their functions. During the RNAi pathway, double-stranded RNAs (dsRNAs) are cleaved into small double-stranded RNA (dsRNA) molecules known as small interfering RNAs (siRNAs) or microRNAs (miRNAs) by an enzyme referred to as "Dicer". Subsequently, these small non-coding RNAs bind to an enzymatic complex known as RNA-induced silencing complex (RISC) that contains a ribonuclease enzyme, i.e., an enzyme that degrades RNA. Finally, the small non-coding RNA (either siRNAs or miRNAs) that are complementary to the RNA target directs the RISC complex to bind and cleave specific mRNAs, thereby silencing gene expression (in this case, by the inhibition of protein translation).
Why are ferns and mosses poorly adapted to a terrestrial life
Answer:
Because they require a WATER medium for reproduction
Explanation:
Ferns are a group of living organisms under the division; Pteridophyta while mosses belong to the group Bryophyta. Mosses are considered primitive and non-vascular plants because they lack true stems, leaves and roots or vascular tissues. while ferns possess these organs, hence, are said to be vascular.
However, ferns and mosses are poorly adapted to a terrestrial life i.e. life on land because they both require a water medium for their motile male gametes to swim and fertilize their eggs (female gametes).
Gaining Insight into Depositional Environments of Sedimentary Rocks
Name: ________ Course:____________
Section:_______ Date:_____________
Sedimentary structures, fossils, cements, and other features of sedimentary rocks provide insight into the environment in which the sediment was deposited.
Match each of the features in the left-hand column to an aspect of the depositional environment listed in the right-hand column by placing the corresponding letter in the proper blank.
Rock and/or feature of the rock
(a) poorly sorted arkose
(b) contains fossils of intact coral
(c) red mudstone containing dinosaur footprints
(d) black shale containing some pyrite crystals
(e) sandstone containing symmetrical ripples
(f) cross-bedded sandstone
(g) contains > 50% carbon and fossil leaves
(h) contains large, rounded pebbles and cobbles (contains fossils of feathers G very angular grains
Aspect of the depositional environment
1. deposited in a desert dune or in a current
2. formed from sediments accumulated in a swamp
3. deposited in very quiet (stagnant) water
4. deposited in an anoxic marine setting
5. deposited by a swiftly moving stream
6. formed from warm-water, shallow marine reef
7. has not undergone a lot of transport immature,
8. deposited close to the source
9. formed from terrestrial mud (riverbank deposits)
10. deposited on a beach
Answer:
(a): 7. and 8.
(b): 6.
(c): 9.
(d): 4.
(e): 10
(f): 1.
(g): 2.
(h): 5. and 3.
Explanation:
Sedimentary rocks are rocks generated from pre-existing rocks and/or once-living organisms. Arkose is a type of sandstone rich in feldspar (at least 25% of this mineral). Moreover, a rock containing coral fossils indicates that its depositional environment was located in warm tropical reef waters. Mudstone is a kind of sedimentary rock composed of clay (in this case, sediments continued to be deposited above the dinosaur footprints). The black shales are fine-grained sedimentary rocks composed of a mixture of clay (in this case, the pyrite crystals are used as an indicator of low oxygen). Symmetrical ripple marks in the sandstone indicate a marine environment where water motion was dominated by wave oscillations. Cross-bedding is a common structure of sedimentary rocks that form during deposition on inclined surfaces of bedforms (e.g., ripples and dunes). Sediment deposition in swamps is usually heavily vegetated and therefore they are rich in organic matter, while deeper swamp sediments are generally anoxic. Finally, cobblestones are naturally occurring cobble-sized stones formed from the flow of water and gathered from stream beds, while pebblestones are formed when water bodies hit the giant rocks in the rivers and lakes.
